Default Turn indicators freezing

Hey everyone, got another problem here, my turn indicators on my 66, work fine until I turn my headlights on, then the right one freezes and stays on, if I turn something else on like the heater fan or put the brakes on the left one freezes on too, if I rev. the motor it helps, now, the strange thing is, I got a new voltage regulator, I've had my alternator tested and it fine, my alternator belt is tight. I have taken the plug off of the turn indicator relay and cleaned the connections, I am out of ideas, anybody have a clue to what can get my indicators to work properly? Thanks!

Sounds like an earth issue to me, have checked all your earth connections?

Let's go to the wiring diagram because that's the FIRST place you should look for common wires.

What is common to your:
  • Headlights (wire #12)
  • Right Turn Signal Indicator Light (wire #362)
  • Heater Fan
  • Brake Lights
  • Left Turn Signal Indicator Light (wire #363)


Looks to me like many of those wires go through the same plug. It's on the bottom and in the middle of the page.

Pull that plug apart and look at the contacts for anything burned or green. While you have it apart, see if those faults go away. - Dave

I can see the plug that I should clean in the diagram, but where is it in the car?

I noticed a short wire that comes out of the fender on the inside of the engine compartment near the turn indicators that look like ground wires, l cleaned those. I heard that the base of the turn indicators are considered a ground, mine are solidly attached to the fenders, should I remove those and clean the base of them? Thanks

Seriously?
Pick a wire. Let's say, a headlight wire. Follow it to the firewall and there you go.

Look at the diagram... it shows the indicator light (on each side) has one wire going to a bullet connector and the lamp holder is grounded. Clean them if you think water got inside. - Dave

I cleaned the bullet connectors, and what I thought was the grounds to each indicator. I will follow the wires, I think the the connection is under the dash near the steering column. I don't mean to come off ignorant, electrical work is new to me, I am learning, I think any question is better then no question and wondering if I am doing it right, or wasting alot of time. Thanks for your responses.

So, the lamp holder itself is the ground, there is no ground wire coming from it? I need to get under the fender unbolt it from the fender clean both surfaces and reattach?

not for testing. Use a length of wire with alligator clips on each end. Clip one end on the ground terminal of the battery, and clip the other on the exterior of the non working bulb's socket. Should the new ground fix the problem, THEN you have to remove and clean everything. In all probability, the ground connection at this light is probably weak and should be cleaned anyhow. Good grounds are very important, but many only focus on the power supply wiring and over look poor or weak grounding connections.
