Default Turn signal indicator being foolish

OK when I am driving at night and have the headlights on, the right turn signal lights up and stays lit. It will blink normally if I use the right turn signal. Is this my electrical system trying to tell me something? if so what?

I asked this question about a month ago. Mine is doing the exact same thing but I have as of yet to figure it out. I will subscribe to this thread to see if someone can help us out. If you get it figured let me know. :thumbs:

I had the same problem with my 73 a couple of years ago. I replaced both the turn and 4 way flashers and never had the problem again. Good luck. J.

mine does that too, and my tach backlight doesn't work. I figured they were wired backwards or something cause the turnsignal light came on and not the tach light, but it blinks normally with the blinker so I decided that wasn't it... sometimes when I make a tight (high G) right turn at night the tach backlight comes on for an instant.

Check the main connector from the dash printed circuit to the wiring harness.

Be careful with those old printed circuits, they can come apart if you look at them wrong.

My 79 was doing crazy things too. I found a break in the solder runs on the flimsey printed ciruit board attached to the back. I fixed the open runs and haven't had any problems since

I have the same problem, however mine only does it sometimes at idle, and if you rev the engine it starts working. I'm almost certain its a bad ground at one of the lights, but I haven't taken the time to trouble shoot it yet. :rolleyes: :cheers:

check all of your grounds especially at the tail lights. you are getting a feed back of current from a bad ground to a good grounding circuit causing the light to light. wcj :party:
