My bike is currently is a few pieces but I am going to be putting it back together starting tonight and I think that this will be super helpful thanks !
Thank you for this. Staring at my SR185 this afternoon trying to work out what to do with its aging electrical system. Led me to an article about making a wiring loom from scratch which led to googling and finding this. I'm not great with electrics but not stupid either. It took me a long time to understand how an electrical system works, and I still struggle with it because I'm better at moving parts, but this came along at exactly the right time for the problem I'm having. You simplified this beautifully.
I agree with the notion of building simple harness from scratch, looks like that’s what many custom builders do. I talked to a guy who said there is a plug and play setup available for these applications, because a lot of people don’t want to deal with aging wiring systems, from my experience mechanics issues are not nearly as big a problem as “old wiring”. Just testing the Old wiring can cause problems, then when you get it repaired you wonder when the next issue pops… grrr. The old “pre-197x”, is not bad, the 80’s onward have caused me most grief.
Brown and red on the rectifier should not be connected. If you do this, your battery will always need energy even when it's off. Right is - red an battery plus, brown on key position 1. Key position 0 the battery plus with fuse.
Awesome video, just wondering if you know if the 2 white wires coming out of the rectifier can get crossed and be OK? My bike caught fire and melted plug, then I cut it with out marking.
Hi I wonder if you can help me. When I go to start the bike. As soon as I press the start button the electrics go dead. after a minute I have again electricity (green neutral light back on) but when I press the start button they go dead again... any ideas ???
Thank you so much for this!! I’m really close to saying the hell with it and rewriting my bike like this. I have something going wrong somewhere in my system, probably a hidden break or corrosion. Anywho, where would you tie in a simple on off switch as well as just a momentary switch for the starter solenoid?
Glad this was helpful! Not really sure where you'd tie in a starter solenoid. I used this motor in a dune buggy and I just used a high amp push button for the starter and never bothered with a solenoid.
is a sr250 the same wiring as a xt250 same year model do you guys think, im trying to get it going but the wires have been riped out by sumone so im a little lost with it
Yeah, for sure. You just connect the tach input signal to the negative side of the coil. It's hard to find a tach that will work on a single cylinder, so make sure you check before purchasing. Thanks for watching!
I just found this and thank you ! I just picked up and 1981 SR185 Exciter with no miles on it(2000k) original everything. Not very exciting, and ugly as it gets,,so off with everything. I’m going to use it for putting around on light trails. Just got it riding better with shock,tires,handlebars and removal of as much plastic as possible. Now the wiring. I want simplicity and reliability, as there is no kickstart. Can these be bump started ? What do you think about getting the components and building a new harness over the winter, like the one above ? Then I have backup ? Also noticed you from the valley, G’day from Fitzroy !
lol... I live in Fitzroy Harbour now :D I used this motor in a dune buggy I created years ago. Yes, you can bump start the motor. I think I have the wire harness diagram somewhere. Send me a private message and we can chat!
@@glassglowz not sure how to send PVT. MSG. Can you send one to me one with an email and I’ll respond with my co-ordinates ? I’ve got the bike running now, however ignition spark comes and goes, suspect battery not 100% but ? Need it to be 92% reliable or its useless to me, i might be way back in the calabogie hills somewhere and have the no ignition spark. We both know that there are “no spark vehicles that stay forever in the hills”. I just moved here and had hoped to use the bike to do some exploring in the area.
@@peterparsons7141 Hey I am in the process of rebuilding a 1981 SR185 Exciter right now and I am also having issues getting ignition spark. Did you ever get the wire harness diagram? Would you be able to email it to me? I looked all over the internet but could not find one. Thanks in advance.
5olaris88 I don't use one on my dune buggy. I just have a high amp push button connect directly from the battery to the starter. Either way, the starter solenoid is not part of the CDI wiring.
Hi, I saw that you added a green wire for the tachometer. Which wire does it connect to? Also, these bikes came with a cable driven tachometer. What substitutes do you recommend? Thanks for your assistance in advance.
It's hard to find an aftermarket tach for a single cylinder engine, so keep that in mind. I'm pretty sure I connected the tach wire to the negative side of the coil wire. It's been a long time though so kinda hard to remember! Thanks for watching.
Hi mate! Don't really know fi you're still answering here, but how do I start the engine with the button? I'm stuck there😅😂 I will apreciate if you help me🙏🏻
Sorry, I'm really not that great diagnosing issues like this. I'd start by replacing the coil, then if that doesn't work you might need to replace the CDI box itself. I had 2 faulty CDI boxes when I used this motor in my dune buggy. You'll usually find all the replacement parts you need on ebay.
Hi thanks for the info and nice vid. Hoping you can help me: I have a1980 sr250 and it will not keep a charge. What should I look for in diagnosing the reason for not charging? And also: it has a hard time firing up and starting. It has a brand-new spark plug and electronic ignition. It turns over fine but it just won't fire up. Once it is warm it will fire up easier. Can you help me with this?
I'd take a look at the regulator/rectifier (thing with the heat sink on it) if the battery is not being charged. Could be a dud battery as well. For your second problem, really sounds like an issue with your carb.
@@dbdb4274 it would be best if you could find an online forum dedicated to that machine (or brand) and ask the question there. I really can't help you much since I don't own that machine.
10 year old video & it keeps on giving. Just got my bike running today! Thank you so much!
I'm amazed as well!

Worked great! Just need to install a starter button and kill switch
Does the circuit also work without a battery? I
Installed the engine in a speedway bike and would like to save weight.
I don't know much about the electrics on a bike but I've heard that the new lithium batteries can't be charged with stock rectifiers is it true?
Thank you this was very helpful life saver
Thank you very much, great video.
@regal7point5 Yes - you should be able to test the bike even with the regulator/rectifier being eliminated.
Brown and red on the rectifier should not be connected. If you do this, your battery will always need energy even when it's off. Right is - red an battery plus, brown on key position 1. Key position 0 the battery plus with fuse.

great demo! I have an 82 and it didn't have the computer part. What year is your SR250?
Thanks man for the help
No problem!

How do you wire a kill switch
Can the regulator/rectifier be eliminated or not used for a total loss system, or to at least get the bike up and running?
where is the pickup coil?

How much diffrent is it with a starter motor and battery. Ps thanks nice stright to the point video
I always just ran a hard wire with a large amp rating push button for my starter. Nice and simple! Thanks for watching.

thanks for the video its exactly what i needed
5olaris88 Great!
glassglowz just making sure i don't work myself into a corner, Is the starter solenoid unnecessary?

Mine is an 82 as well.
Hi mate! Don't really know fi you're still answering here, but how do I start the engine with the button? I'm stuck there😅😂 I will apreciate if you help me🙏🏻
I didn't use anything from the original harness to start the engine. Just use a hi-amp switch and run 12 volts to the starter.
The 2 strands of the bobbin connecting the candle found on the cylinder of the speck, GND.
What burned?
Thank you
Sorry man, that sentence makes no sense to me! Thanks for watching though :)
The orange and red wire that is connected in the reel, touched the mass, earth, ground.

Hi I have a 1985 yamaha xj700 trying to wire it up with minimal wiring. I can get it to turn over but am getting no power to my coils can you help?
Sorry, I'm really not that great diagnosing issues like this. I'd start by replacing the coil, then if that doesn't work you might need to replace the CDI box itself. I had 2 faulty CDI boxes when I used this motor in my dune buggy. You'll usually find all the replacement parts you need on ebay.
Hi man,yamaha ttr 125l cdi how to wire?
Is the computer the same as black box
Yes, same thing.

+thewingenuity I have this same problem! Mine is an 81 sr250. Wont hold a charge. Did you ever fix the problem?
Great vid, but no need for the starter solenoid?
+ds dray I didn't use the start solenoid. I just used a button that could handle the high current load.
Hi... Would this example work on a 92 South African spec SR 250?
I really have no idea.
I have a Honda xr 125 L 06 will this wireing tutorial be similar to my bike ??
Hard to say. I'd start by finding a good wiring diagram and then taking it from there.
Yamaha enticer cdi wairin how to fitting
Is the cdi a 5 pin or a 6 pin? My one is a 6 pin
Not sure and I don't have the unit to check anymore. Thanks for watching!
if u now we're to buy a wiring harness can u please let me know thanks ??
+Tony Jamel eBay is your friend ;)
yoooooo I have a 1987 Yamaha 225 Dr 3-wheeler shaft driven the wiring is fucked would this work u think?
Probably not...
Can this be done with a klx650
I highly doubt it. Thanks for watching though!

I have no idea.
Where is fuse 😂
Well you'll need to add one obviously 😆
Sr good day.. Where to. Buy yamaha exciter Sr 250.. CDI????
I'd check ebay. I bought a few CDI units off ebay, but that was many years ago now. Parts are likely getting hard to find.
@@glassglowz can we just used a deferent cdi from other 250cc motor
@@kevinricbalberab9558 I really don't know if that would work.
