Turn signal indicator lights come on with key Options

[GeorgeKopf]

I'm wring my 1973 wiring harness and have a bunch of things installed which seem to be working correctly (i.e. headlights (high & low beam), headlight motors, turn signals, running lights, tail lights)

But (IMG:style_emoticons/default/bootyshake.gif) the turn signal indicators are always on!

I've traced the flow of current from the fuse panel (red with white stripe) to the hazard switch, from there (red) to the relay and from there to the turn signal indicators (blue with white stripe).

47 is the relay
31 is the hazard switch
22 is the turn signal lights
26 is the steering column switch


I have two relays and both seem to work fine. When I pull out the hazard switch the indicators and lights all blink. When I set the turn signal that side blinks.

I have two hazard switches and both behave the same way. As soon as I connect the red and red/white wires the turn signal indicators come on.
With the knob pushed in, I have continuity between the red/white (power in) and the red (power out to the relay).
With the knob pulled out, I have continuity between the black/red (power in) and the red (power out to the relay). (IMG:style_emoticons/default/confused24.gif)

More information:
I have cleaned all grounding studs.
I disassembled one of the relays and cleaned it.
If I disconnect all of the wires from the hazard switch except for the red/white and the red, the signal indicators come on and stay on. Doesn't this mean that my relay is bad? It should be getting power so that it can feed the turn signal indicators when the turn signals are set.

It seems that the relay is allowing the input power to the blue/white wires when it shouldn't.

If so, is there a good way to test or repair them?

Thanks in advance for any advice.

You can read the rest for context but the answer is in the above link.

Turns out what I'm experiencing is classic with LED headlights.

My wiring harness is a 1973. There are two white/blue wires connected to my #1 fuse. One comes from the fog light relay and the other goes to the high-beam indicator in my tachometer.
......
I tried grounding them both. This solves the problem of switching to the high-beams and the relay now provides power to the fog lights. But the high-beam indicator doesn't work anymore. I'm guessing that I need to cut apart the two white/blue wires and only ground the one coming from the fog light relay.

Do I have this right?

Thanks.

Correct about the high beam indicator. My '71 was not wired with 2 white/blue wires. The white/blue for the fog relay had to be cut from the larger white wire on my 914. I suppose you will need to do the same. Just figure out which white/blue wire is from the foglight relay and cut it off from the other white/blue.

Thank you both very much for this golden nugget of information. I had been wondering why there were two white/blue wires on the connector when the directions for the fog light fix only indicated one. I hadn't even noticed that my high-beam indicator stopped working.

I cut one wire off the stock plug, soldered on a new plug, and now I have working foglights and a working high-beam indicator light. (IMG:style_emoticons/default/piratenanner.gif)
