MY 1975 yAMAHA dt400 SIGNAL LIGHTS DON`T FLASH?

Question

I replaced the flasher. They still don`t flash. They light but don`t blink. Anybody got the answer?

Answer 1

I have had that problem before. Once it was the flashing relay, the other the voltage wasn't enough so that the relay wouldn't make. If the lights are a marker and a turn signal light you may have a short somewhere. Make sure they are grounded good. check to see if you have proper voltage at the flashing relay.

Answer 2

you might want to check for any cuts in wires.I had this problem on different bike and found a splice in wire.Once a fixed this they worked fine

Answer 3

flasher units are very fussy about what globes are in the blinkers. Have a look at the flasher unit. It will have written on it what globes should be used. Then make sure  the globes are the same as specified on the unit.

Answer 4

Make sure all the bulbs are the correct voltage. 12v not 24v. Check all bulbs are working. If new relay is correct one then it may be a duff.

Answer 5

Sorry no answer here,but when you find out,please let me know.I am having the same problem with my Yamaha RT180.

Answer 6

Check the battery.

The battery activates the tail light and turn signals.

If the battery has a low charge, it won't have enough power, to light the tail light and operate the turn signal relay at the same time.
