Question about 2005 Yamaha YZF-R1
Posted by Anonymous on
Hi, Anonymous if your headlight is not working, 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.

It sounds like you have a poor ground connection. You'll have to disassemble and check the wiring harness for broken wires, start up near the ignition switch or around anything that is no longer stock on the bike (like aftermarket turn signals, fuel nanny, power commander, etc.)

Sounds like the rectifier has gone bad, overcharging the battery and cooking wires. Your best bet here is to take it to a dealer rather than risking putting in new parts then frying them the first time you ride the bike again.

remove the bulb and test with a multi meter that you have power at the high beam socket. If so it is probably corrosion on the contacts. Clean with a plastic scourer and re fit the bulb. If no power there then test wiring for a broken wire or a dead relay.

That is probably the handlebar hi / lo (or lights on / off if fitted) switch or no power to it
Check for power at the headlamp fuse
If no then suspect the ignition switch or wiring / connectors to it
If yes then check for power going into handlebar switches
If no then check wiring / connectors to them
That will isolate the problem for you
