Left turn signal doesn't blink

[VinnySem]

Left turn signal comes on but does not blink. Right one operates normal? How to fix?

Do both the front and back ones come on? Usually, if one is burnt out, the other one will not blink.

Also, does it not blink at idle, but will blink at higher engine speed? Simply a matter of low voltage.

Another possibility is incorrect bulbs. Not sure what the standard (original) bulbs were, but 1156 will work for the rear bulbs.
If your front lights are also running lights, they should be 1157, otherwise, 1156, like the rears.

as with all lighting problems the first thing you should do is check and make shure all your grounds are good . the flasher unit would be my next stop. i am shure it is one or the other.

Also, you should check the ground wires in your signal lights. When I got my bike the left front didn't work, it was just a broken ground wire.

If the unit only has one wire going to it, you probably have a weak or bad ground. Check the mounting to the frame for good metal to metal contact. You might also try swapping bulbs with the right side and see what happens.

Both front and rear come on, neither blink. Lights come on bright. 2 wires run to each light.

Check out your ground wires then. One of them are not making connections, it may even be in the socket.
