Question about 2000 Yamaha YZF-R1
That's right side blinker lights don't work
Posted by Anonymous on
Hi, Anonymous before diagnosing any turn signal/running light/parking light issue make sure the bulb is good and the light fuse has continuity with a test light. If you have replaced you OEM lights with LED lights you are going to need a load equalizer. If no turn signals work the cause could be a faulty turn signal module or the connector going to it, look for corroded, loose, or broken pins/sockets. Contact spray cleaner is great for removing corrosion. If your speedometer does not function properly it will have to be fixed first because your turn signal module gets the data from the speedometer for normal turn signal function. If your front turn signals don't work use a test light to check for power and ground at the bulb socket, then start backtracking the wiring through every wire connector to the turn signal switch/button and check for continuity, go all the way back to the fuse if necessary to find the cause of the malfunction. If your rear turn signals don't work check your rear fender wiring harness connector first for corroded, broken, loose pins/sockets, power, and a good ground, (the harness connector is usually located under the seat on the front of the rear fender) then keep tracing the wiring look for obvious harness damage caused by the rear tire. If you still can't find the malfunction backtrack from the rear fender wiring harness connector. If one side does not work you could have a faulty turn signal switch or module check for continuity.

Hi there! nice bike.. i serviced this type of bike before.. Anyway, I can see you replaced the relay (make sure it is compatible)... if other circuits fail there maybe a wire shorted to the ground (chassis).. check it physically for wear. Replace main fuse or better, check the fuses.
hope this helps.

The service manual has a wiring diagram, but you will have to zoom in to read the wire colors.

SOURCE: I have a 1978 yamaha
I used to have a 76 XS500. Got lots of compliments with that bike.
The wattage of the bulbs is important on how the blinkers work. The rate they flash, and if they flash is dependant on the current being drawn from the lights. Thats why many times if you have one light out the remaining light may stay on solid or flash faster.
You could try removing one bulb on each side and see if the blinkers work. Then reinsert and remove the other remaining bulbs. If they work normally with one bulb in each side whether front or rear then I would suspect the flasher relay.
Say the fronts work when the rear are out and the rear don't work when the fronts are out then I would suspect either the bulbs or sockets or your solder connection or switch.
You may also look into an electronic flasher. They automaticaly adjust for variable loads to flash so they flash at a normal rate.
