Signal lights flash fast on one side, and nothing on the other side at all. Bulbs are good.

 

Look in the manual sticky in General Discussion.

It sounds like you have a loose connection on the blinker connections. Unplug both of them, then reconnect.

 

If they are flashing fast there is not enough resistance in the system, have you modified it recently?

 

I agree with not enough resistance, if it's not a loose connection...is one bulb different than the others?

 

I just got it, and has been this way since i bought it.
The guy i got it from changed out the rear lights because the former former owner put LED's on the rear.
So, i was going to try to put it back to stock, or close to it.

Thing that puzzles me is if you have it on the left blinker for a while(the one that blinks fast), then switch it to the right, you can hear the relay blinking 3-4 times then quits. But during that 4-5 times, the lights don't blink.

 

My guess is the previous owner didnt put the left side together with the proper lights or might have missed a light. Possibly a bad switch on the right, if its clicking it should be sending out power and it shouldnt stop clicking until you turn it off. get the multimeter and see if your getting power from the switch and if you cant find a problem with the left side you can put a resistor in to slow it down. Let us know what you find.
