Full Inspection of the FZ6 Charging System
Vložit
- čas přidán 26. 08. 2024
- In this video I will be checking over all the specifications and tolerances for the charging system circuit guided by the factory service manual on this FZ6. I will show you how to check your stator, regulator rectifier and battery. I have struggled over the years to keep the FZ6 charged and happy which has lead to me taking a deep dive on the entire charging circuit. Below are the relevant specs to this diagnosis.
Stator coil resistance spec = 0.22 - 0.34 ohms
Battery should be above 12.7 Volts when disconnected from system
Battery should be over 14.0 Volts when revved at 5000 RPM

My 07 has just started doing this at 25k miles.
I'm happy it lasted so long. Never even changed the original battery
Switch to an LED headlight and tail light. That will remove about 100 watts from your system without reducing light output and will likely solve your low speed charging issue.
I just have a kill switch for it
What type of LED are you running? Names please
Thanks for your video. I have the EXACT same problem on my 2005 FZ6...and, it's because I haven't wanted to take the RPMs over about 6K..... You explained a LOT here!!!
Glad to hear the video helped you! With the FZ6 you definitely gotta keep the revs up just to keep the battery topped up. I've gotten into the habit of lightly revving the bike to 3k rpm if I'm sitting at a long light. I wish it wasn't this way but oh well.
Yeah I'm actually electronically limited right now due to power of the battery so I'm going through all the usual suspects of what is causing it I can only do about 5,000 RPM Max right now and I have to keep the bike at 3K RPM while stopped just to be able to move from a red light or stop sign and on top of that it has to be at 3000 or higher just to be able to begin moving without falling on its face
Brilliant video, thanks very much!
You're welcome!
I have no idea how I got to your channel, but I'm glad I did, very detailed videos, I hope they get more views though, really hard job done on your part! Great job bro! I just got the fz6 '05 model, and maybe your videos might come in handy at some point. Thanks!!
Thank you! Glad you found the channel. Hope you enjoy your bike!
here i am again .... using your videos as a point of refence - gd work
Happy to help 👍
Good video, fz6 are notorious for weak charging systems. I found the easiest answer was to buy a battery trickle charger, install a convenient lead from the battery and hook it up overnight every few days or once a week.
I too found a trickle charger helpful, I would just rather not have to do that haha.
Great Video. I have exactly the same color like you. So much fun riding it. It's a great bike dude 🤙🏍️
Very helpful video bro! I just got my fz6 and am facing charging issues, your video just gave me a big help! Thank you form Cape Verde Island!
Glad the videos helped you! The biggest thing that helped my charging issue was raising my idle to the proper 1300 +/- 50 rpm. Ever since raising the idle my battery situation has been much better.
Really appericate your video and you taking the time to help others out, hopefully I get money sorted thanks
Happy to help! Hope you get it sorted 👍
Thank you very much for your great video❤
Great video. I've just payed for a new battery and 2days after not using the bike I go to start it and it's dead.thanks for the tips.
This video is so helpful, thank you!
Glad it was helpful! 👍🏍️ enjoy the ride
Thanks for the great video man! Yeah, I am having similar problems. Battery seems to cut out even when I am riding the bike. I came up on a stoplight the other day and the engine cut out. Bike wouldn’t start after that. About 2 minutes later it started up again. I made it another mile and it did the same thing at the next stop light. Luckily a guy swooped down from a nearby apartment like Batman and helped me jump it. I didn’t make it out of the parking lot before it died. It’s happened a few times: the lights and display go out and the bike dies when I stop revving it. I did leave it on a while back and killed the battery. I am taking that in to get tested, but it sounds like I’m gonna be testing all these parts.
Hi Calvin, loved the video but don't experience the problems you mention. On my third battery from new (2008) and this current battery has only been flat once in it's 5 years of service. I charged it up and had no probs since. I usually only ride it for an hour or two a week and don't rev it extremely hard. It's been super reliable and I never really had any trouble even though I have two front lights on all the time and heated grips. Also have a gear change indicator wired. Greetings again from Australia, cheers, Pete Bosch.
Very informative video. I have had kind of similar problems as you, that after a short ride, my bike wont turn back on and I had to jumpstart it. I checked everything, stator, rectifier, fuses, wires and brought a new battery. Now it's starts every time, but im worried that it will happen again because of the rectifier. I measued the carging voltage of the rectifier at around 5.000 rpm and the voltage cuts off at 13,47v, which I guess is not enough. Im planing of replacing it, just have to find a place to buy it. :-)
I had a very similar problem with my bike not getting past 13.5 ish volts. I concluded it was mostly due to the battery and short rides. Back when I was having that issue I would throw a battery tender on the bike once a week just to keep it topped up. Good luck and stay safe!
Awesome video dude! Thanks will come in handy 4 sure in the future
08 FZ6 with only 14 000 km on it, I recently replaced the battery start of the season and I found that after it has sat for about a weak it has power but not enough to start. Excellent video to give me some information on where I can start trouble shooting. Not having a tender attached to the bike (the first 5 years of the bike it would start after sitting for the winter first crack every time) I have to open the gas tank up every time I want to put a trickle charger on it. I do tend to ride only short periods. At most 30 mins of riding mostly highway. However been finding after I drove it 2 days in a row for about 20 min rides each the third day I went to take it out the bike wouldn't start. Thanks for the advice and easy break down of steps to get closer to figuring out what might just be the issue.
It sounds like you have a parasitic drain on your battery. As in one circuit on your bike isn’t completely turning off when the key is out. Sometimes heated grips or accessories do that. I’d recommend getting a multimeter and reading up on how to find parasitic drain. Best of luck!
@@Calvinm After going through all the steps it does appear that once the battery was fully charged and unhooked it held around 12.64 only dropping slightly. Stator and Rectifier both seen well. I feel the charging system is doing it's job. But something somewhere is causing the battery to drain. The bike is completely stock with no aftermarket addons and from what I can see everything seems to not have any frays. Bike has never been dropped. Next step I'm guessing will be to look for continuity between all the wires. And have my battery tested since its under warranty and should be free just incase there is something I'm not picking up.
Nice video! Can you make a video of installing the heated grips
I sure can!
Tank you ❤❤❤❤❤
You’re welcome! 👍
I just traded my seca 2 for one of these 😅 find it hilarious I end up on the same channel for repair tips.
Wild! What a coincidence. Maybe you’ll pick up an FJ09 next 😂
"F said 6" ??? Lol pls explain awesome vids btw I have a 2007 as well, these are helpful 🎉
Haha I don’t know. I’ve also said F zed 6 instead of F zee 6. Glad you have found the videos helpful. 👍
Just swap in a Vortex 15 Tooth, 530 steel front sprocket (Product# 3516-15) to alleviate that issue of riding slow and achieving peak power. Going down one tooth on the front sprocket will cause the bike to rev higher at lower gears.
That's an idea! I do a lot of highway commuting though so I don't think I would enjoy the added revs on the highway. Thanks for the tip
I have had my FZ6 since 2005 and haven't had any problems until yesterday. It is a great bike. I bought it new and never felt the desire to get another bike. Its got good pull, agile, and is fun to ride. It is also very versatile.
I tried starting it yesterday . The motored turned over with no problem but with no ignition. It might be an electrical issue. It got a major tune up and overhaul about 2 months ago. The battery didn't seem weak at all. So I am a little puzzled.
very informative video!
I ran into some electrical issues recently and ended up replacing the stator as the old one looked burnt out / corroded. After replacing it, the bike is charging great (13.5v idle, 14v 5k). The resistance on the stator is high though - it's reading 0.7 ohms. my multimeter has resistance of .1 so that would make it 0.6 ohms. it is an aftermarket stator that was advertised as more powerful than the original. do you think the high resistance is a problem even if the bike is making the proper charging voltage?
It sounds like you're getting the appropriate voltage at the battery. The resistance specification may be slightly higher on your aftermarket stator. Maybe contact the manufacturer of the stator to get a spec from them for what a good condition stator of their's should measure. It probably won't be an issue, probably just a slight material or winding difference in the stator. Where did you get the stator?
Good job! Problem solved .Thx! 👍
Awesome, love to hear that!
Only running dual headlight mod and never issues with voltage. 2005
❤❤❤ thanks
Hola kevin un saludo tambirn me pso a mi lo que dices de la bateria si no acelerad mas de 3000rpm al ir en ciudad y parar varias veces y volver a arrancar al final se descarga la bateria un saludo y gracias por todos tus videos yo tengo una fazer s2 del 2009 y muy contento
Weird, never had any charging problems with my 2006 FZ6. My battery is more than 5 years old Yuasa and still strong. I do not even have any issues with starting the bike at near 0*C temperatures. I put more than 2.5kkm this year in temperatures below 10*C with heated grips (55 W power) almost constantly turned on and everything runs perfectly. I only had an issue once when turn signal relay ceased to cooperate, but it started to work again after I restarted the bike. Also I had to replace a starter due to the fact that the brushes were completely worn out and I would get error code 12 due to this fact out of nowhere.
That's great you've had no issues. This kinda confirms my belief that a trouble free bike stays trouble free. As soon as one charging system component starts to get weak it takes another down with it. Or maybe that's just my jaded perspective haha.
@@Calvinm yeah. Though I have the older version of the bike (pre-facelift). Still, no idea what could be the cause of the issues on yours. Definitely running the diagnostics of the entire charging system could help. Or checking for any parasitic power losses.
Hi. I have question. Yesterday check engine light came on. And that was about error 46. So I measured stator coil resistance - 0.29/0.30 thats OK. Than I measured battery when disconnected from system I got around 13.1 volts thats OK. But when I measure battery voltage when I rev at 5000RPM I got way above 17volts and keep increasing. Thats not OK right? So I need new regulator. Please respond, because its bike season and I got this check engine light. How bike rides nothing changed and nothing tells about problem but I don't like that check engile like and error 46/
Hi Rihards, yes going up to 17 volts and climbing at 5000 rpm does sound like you have a bad regulator. It makes sense that your battery rests at 13.1 because it is being overcharged. Your battery with everything disconnected should be closer to 12.6. It is usually recommended to change your regulator and rectifier at the same time because they are so closely connected but I've changed each part individually before and not had any issues. Best of luck!
@@Calvinm You are the best. Minutes ago I got new regulator from store and just changed. And woalaaaa. Brilliant. No check engine light and everything is fine.
Happy to hear your bike is healthy again! 👍
hi again :D if I start the engine and disconnect the battery, would it still run, or engine need battery to run, as it is injection and so on? I mean can this method be used to check if generator is producing power to the bike, or energy is taken always from the battery?
There isn’t a test in the factory service manual that involves running the bike without the battery connected to test the power of the stator. I wouldn’t recommend doing that either because it could overload the stator and cause problems. The bike might run with the battery disconnected but I could be wrong.
@Aivara83 did you tried it?
@@kmetmosnja6341 can't remember, I think I didn't try and I can't now, because my engine exploded 🤣 I have a 2 inch hole in my engine now 🙈
@@Aivaras83 ouch, how that came to be? 🤔
@@Aivaras83Yes what exactly did you do when that happened cuz we're not trying to have a 2-in hole in our motor either
Lately I moved my fz6 Yamaha 2007, from my garage and put it in my back yard, now my bike won't start. It tries to turn over, but when I rev it, it's fighting to get the gas to rev it. In the past I had battery problem where I have to keep my bike charged over night, and now my bike won't start at all, even when battery is charged. Now my head lights won't even come on, need help my bike community, is it the regulator, I know for sure I need new battery, but what else could be the issue
I would change the battery to a new one and then assess what charging voltage you are getting when revving the bike to 5k rpm.
@@Calvinm thanks will do, crossing my finger
My battery shows 12.7V. when I start shows over 14V, when I rev numbers goes under 14V, but over 13V, is this normal, I have 2 cylinder 700cc.
Sounds a little odd. Usually voltage would increase with revs. But your voltage with the bike off and at idle sound fine. It would only be a problem if the bike went below 12.6 while revved. Either way I would consult the service manual for your bikes specifics.
Hi, by any chance, maybe you know why my rear bulb shows higher voltage than brake light? Also, why horn voltage drops to even 4V when I rev the engine? My battery shows 13.05 V when off, and when I start and rev it not going higher than 14.35V, so regular should be ok. Stator shows all 3 connection the same about 0.2 oms. Basically I changed stator and after one day I saw my rear bulb not working, when I changed it burnt straight away when I turned the key - ignition ON. Trying understand what is going on. I had additional horn on, I took it off now, I thought maybe it is same circuit and I switched wires on horn or something 🤦♂️
my fz6 voltage wont shoot up when revving instead will slowly increase to 14 v at 5000rpm however as the bike warms up voltage will drop. cant seem to find the problem. have changed rectifier and stator. i tested the stator got 50acv
and i tought im the only one.my battery lasted like 1.5y .. will upgrade to never yamaha at the end of the year.prolly fz8
HELLO . I did as you said and I see a multimeter 0.0.. I started the motorcycle and it shows 13.8 need to exchange?
I have a problem with my Fazer,,i just change the batteray and only work two day,,,after can't start...so i think the batteray is won't charger...do you have any idea???🙏🙏🙏🙏🙏
Sounds like your battery has a parasitic drain. It's possible a component of the bike is draining your battery. Try charging the battery but leaving it disconnected from the bike. If it holds a charge over a day or two, then the battery isn't the problem.
You can use a multimeter to search for a drain on the electrical system, but that's getting a little technical.
@@Calvinm i ready buy a new batteray,but only work two day,,,and this morning i found one cable from a left side go to main a regulator part looks burn,
did you ever find a long term solution for the inherently weak charging system?
I'm experiencing the same on my (bone-stock) 2012 FZ6R :(
I saw someone recommend a swap to LED lighting which is a good idea...
but idk how much of an impact that would have overall.
seems like a fatal design flaw and caused me to have to get my bike towed back home recently.
side note: my idle rpm is ~1600
There was no better solution than keeping the idle at the correct spec and making sure all components are within spec and working well. Also make sure any accessories aren’t draining your battery like extra lights or heated grips. I found a new battery really helps. If your battery is a few years old it would be helpful to replace it. Best of luck!
@@Calvinm ty 🙏
I've had problems with my Fz6 not being able to start after idling for a while, or going for a short ride and stalling the bike. I've had to roll start it several times. I checked the battery and its 12.84 volts when off. I checked the voltage at 5000 rpms and it doesn't get above 13.5 volts. I'm going to check the stator but what do you think the problem is?
When you measuring stater, these 3 wires, resistance (at 5:00 min) do I have to have battery in?
Yes, it doesn’t matter if the battery is in or not. When the plug is disconnected it has no connection to the battery.
@@Calvinm sorry, I meant, do I have to have battery connected? 🙈😁
What's going on everybody?
I'm just watching a CZcams video about how to fully inspect the charging system of the Yamaha FZ6.
😂😂😂
man I have a error 1, when i press the starter button it turns over but the instruments reset and error 1 again.
Yikes thats a tough one. Error one point towards an issue in the main wiring harness connection to the ecu. Check the coupler for pulled out pins or moisture and corrosion causing problems. If that doesn't show anything out of the ordinary make sure the wires between the dash and the ecu are not shorted out anywhere. This will either be a really simple solution or a lot of head ache... Best of luck. Shoot me a message on instagram @freeheadgasket when you figure it out!
Can we get a paint tutorial 😄
Have same problematic
CODE: 33 34 .. I replaced Ignition coil .and still show me the same problem... He also shows me a code 62:1.
Ya code 33 and 34 point towards the primary side of both ignition coils. Check the wiring on the primary side for a short or a bad connection. Also check the resistance on the new coils to ensure they are up to spec. Code 62:1 means the bike has a history of one code, which doesn't really help this trouble shooting. Best of luck!
Thank you very much I will check ...
I got no problems yet, but also have no heating system or double lights activated. Just one time run out of battery because i accidentally worked with parking lights on on the bike and recognized it too late. I push
started it and later on no more issues.
Are you planning on change the turnsignals or taillight? I'm thinking of led convert it, maybe could help to safe some energy and looks fresh with the led daylight combined with turn signals
I hope your FZ6 stays problem free, its a good feeling. I haven't explored the LED options for turn signals or tail light but I'm going to look into it over the winter. Thanks!
I have a question about what is causing the battery to discharge, I replaced it with a new one day driving and the other day the battery overnight discharged to 4 volts, I do not have GPS tracking, I only have heating grips that are turned off together with the ignition
Hmm that does sound strange. The only things I can think of are that the new battery is bad from the manufacturer or there is something draining your battery while the bike is off. Try reading about parasitic battery drain and test your circuits to see if anything is pulling power while the bike is off. Best of luck!
I found a problem, previously I had a problem with rectifire, which charged the battery up to 18 volts, I damaged the relay from the heating grips, which after turning off the ignition constantly gave voltage to control the heating grips and thus discharged my battery
@@Calvinm Damaged heated grips caused a short circuit and damaged the relay that discharged the battery while not using it, unplugged all the extras that were connected to the battery, changed the battery and problem resolved
It also shows a fault code
What fault code does it show?
Just noticed my 2005 battery died after starting it 4 times fml
15,5 Volts it's too high! One should never exceed 15.0Volts charging 12v batteries!
