Question about 1980 Yamaha XS 650 G
Bike started no headlight. Removed dimmer switch, a few wires popped off the blinker switch. Resoldered put back together. Now start button does not work and cannot kick start bike either. Still not headlight. Have power at the start switch and in the headlamp assembly. What to check next?
Hi, Ludwig if your headlight is not working, only one beam works, keeps burning out, blinking, or is dim the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, then check your head light bulb socket ground wire for a clean tight connection, that being said the usual suspects are:
1. Faulty ground or power supply wire to headlight bulb socket.
2. Worn down solder contacts or loose fit of the bulb base in the socket due to vibration.
3. Worn, chaffed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi/lo beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty wiring between battery positive and headlight bulb socket.
9. Weak charging alternator/generator.
10. Faulty voltage regulator/rectifier ground or overcharging.

SOURCE: bike only fires once
Okay, let's have a look at it. Say Ahaaa.
The probable cause of the problem is not the spark. Get a fresh set of Stock NGK spark plugs, ground the plus to the engine, and check each cylinder for spark as the starter button is pressed for 3 seconds or so. I will wager that the spark is present.
The likely problem is the fresh gas was put into a very rusty gas tank. Bits of rust now inhabit your carb and are having fun plugging up the carb. Look at the gas valve. With a little luck there is a small bowl behind the valve. Remove it and tell me what you see in the bowl.

use a test light to find out if there is power going to the starter. take the rubber cover off the top of the selonoid. it should be some where near the battery. one post of the selonoid should have power constantly and the other one should not untill the start button is depressed. if the light lights when you hit the button, there is either a problem with the power cable going to the starter or the starter its self.

Push the starter button if your hear the solenoid clicking the starter button is good. If there is no click from the solenoid you may need to clean or replace the starter button.Follow the positive battery cable to the starter solenoid. Jump across the two cable terminals, this should activate the starter.If the starter works now you have burnt contacts inside the solenoid. replace the solenoid. If the starter does not turn over, try again tapping on the starter with a plastic hammer if the starter works now you need starter brushes. If the starter will not turn over with direct power (bench test) and the brushes are good the armature is probably shorted. You will have to replace the starter as an assembly parts are not available to rebuild the starter.
