Question about 1981 Yamaha XJ 650
Just got done putting some parts on my bike all winter and got it back together today. went to try and start it but nothing happened. Its in neurtal(this light and the tail light lights up but weak horn) and I went through all the fueses and wires and nothing was out of place. I tryed boosting it and still nothing but what I did notice that the battery acid is really low. would it probley be the battery giving me the problem cause it ran fine when I parked it last fall.
Hi. Yes more than likely it is the battery. Even when boosting it the battery can drain all the power from the boost battery. You could try topping up the acid then charge it.

SOURCE: electrical trouble
If all the fuses turn out good especially the main fuse then you might want to check your starter solenoid. Try jumping the two leads on the solenoid if the bike starts then most likely the solenoid is bad. If it doesn't start then it could be two other things. 1- your Ignitions might be shoot. tell tail signs. Bike cutting out during the ride and bike loses power when you hit the starter button but power returns when you turn the key off then back on. 2- The Rectifier might be gone. The rectifier will cause many different problem that might have you chasing carb problems, to the bike won't start at all with no cranking

sounds more like a fuel problem to me. is it cold there did you use stabilizer in the gas? try some berrymans B12 in the gas it cleans everything up internally. it worked for me

Need to check the ECU for registered malfunction.You must take it to a dealer's workshop.Engine warning light means that a sensor is not working properly.

try cleaning the battery terminals, check the battery voltage when you hit the starter, If you run it too long and it isnt charging a good battery you can damage the regulator again, same if you jump it off a car battery, it can cause damage
