    To load test a battery without special equipment..put your meter across the terminals..read say 12.5 volts..then crank the bike..if the meter indicator drops to 10Volts or less its probably a bad battery...

    Nice video, simple but to the point. Load test is a great way to find those batteries that seem good, take a charge, and frustrate the heck out of you when it won't crank more than twice before it clicks!

    Before jumping to any conclusions, go around and tighten ALL high current attachments. Start with the negative side of the battery and snug it up. Follow the negative wire to the frame ground and snug it up. Snug the positive side of the battery then follow the wire to the starter relay and snug it up there too. On the other side of the relay, snug the wire that goes to the starter and then finally, snug up the wire on the starter motor. ANY connection that is not tight will fail to pass high current at voltages of 12 - 14 volts and this is, by far, the most common "starter" problem that comes into our shop.
    By the way, when you press the starter of a bike (even if it's in neutral), hold in the clutch because many (but not all) bikes have a switch in the clutch that will prevent the start button from supplying current to the starter relay. When you test the starter as shown in the video, be ready because it will strongly try to jump out of your hand. Probably best to do this test near the floor so the starter won't have so far to fall and expect that there will be a large spark when you first touch the jumper wire to the starter. If the motor drags, draws a lot of current and gets hot while spinning, replace the starter.
    As it says in the video, if everything down to the starter, including the starter motor is working, but the engine won't turn over, usually you have already noticed that the headlight dims when you press the starter button. Something has locked up the engine and it's NOT the starter no matter what the bike's owner thinks is wrong. Do your own testing, don't rely on what the bike's owner THINKS is wrong.

    My brother's bike WR250 main relay is not being controlled by the ECU, I jumped the main relay blue wire to ground to get the bike started. The ECU has good ground and 12v supply, all wires from ECU to components has continuity, start, clutch, neutral switches are ok.
    All these tests lead me to believe the ECU is not grounding the main relay control wire, my temporary solution is to control the relay via a switch to ground, run the bike and check if the ECU gets hot, if it's cool then he can use the bike untill he orders an ECU.

    Nice video m8,bravo! I never like electricity problems on dirt bikes or to be honest at all my bike's.But my starter is doing a sound like almost ready to start but 1 time or two times then it starts those clicks.&when I charge the battery it's okay for a week.(new battery)Weird cuz 2 times same problem.

    My 19 yz250fx acts like battery is low, push starter, I get a click click then it slowly at first then it seems to kick in and spin at the right speed, what could that be? Just by watching g video I see that the clicking I'm getting is right, starter is dragging at first then kicks over faster, I guess that's a bad starter?

    my 2009 wr450f starts ok with a brand new charged battery but after a couple of days the battery does not retain the charge and doesn't charge any more. If I charge the battery outside the bike with a charger the E-starter works only for a couple of times the the battery is done, I clamed the warranty and now I'm about to decide wether burn my third new battery or sadly just keep kicking the bike to start forever. My technician says it might have a short circuit or a energy loss somewhere, he doesn't know. My halogen bulb seems ok as the type the manual says 35/36.5w so hopefully is not a car type bulb. Any idea?. The bike feels just fine to ride with good engine power and the light seems strong and normal for night riding, the voltage is producing I remember is over 13.5v so the battery should be charging normally although because there's not ytxz7s 6ah size where I live, I'm using ytxz5 4ah. It's a carbureted model so 4ah should be enough my mechanic says.

    So my wr450 has kick and electric start. Haven't pulled my starter out yet to bench test but. Question is.... ill hit button to start and just get a click. Then go to kick and its like the motor is locked up till I put it in gear and rock back and forth till its free. Then I can kick start but starter still just clicks. Can a bad starter cause my kick start to lock up?

    Can somebody help me out please before I scrap my bike 🤣🤣 my 2018 yxf 450 just died when I press the stator button it just ticks like it's a dead battery but it is not I tested startor was bad sometimes work sometimes didn't I striped it down brushes where wore down one side I replaced all bushes and springs and solenoid beside battery and still the same ting what I did notice though do when I use multimeter put it on battery shows over 13v when I push the button it drops to 0v I thought was a bad battery changed it still same thing and with the solenoid with out pushing the buttons measuring from red cable side to black cable side reads over 13v but same thing when I push the button just ticks and reads OV I'm bringing to think the solenoid is a bad one would I be correct I would have thought with out touching the starting button there shouldn't be a voltage reading across those connections ???

    • @rmatvmc

      It's most likely because your bike has a neutral safety switch. This will have to be disabled for you to be able to use your electric start while the bike is in gear. You can do a quick search online and find what other users have done to disable this switch.

    Kinda barely touched upon this at the end: everything gets dirty and a little "out of whack" riding trails. I would think the first things to check would be all the safety switches that prevent the start of a bike on purpose such as the clutch switch, kickstand switch etc.

I can actuate the starter button and i hear the fuel pump turn on but i get no click from the starter relay and no power to the starter motor. You would think the starter relay is the problem but i can take the relay off and make it actuate(click) when i put power to it. I also installed an OEM replacement starter relay and still doing the same thing. Anyone have an idea what could be going on? checked all fuses, starter button is good battery is good

He gonna be miserable from battery/aluminum problems every week if he goes fast through trials or free style in the forest its 1of the worst bikes even for not beginners.Give your$$$at YAMAHA ofcourse but before aluminium,except if you are a Motart boy&you make dirt bikes like circus with wrong rears wrong tires wrong philosophy 100%for a five short gear bike made for mountain or races;)
