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.

Before I start a new thread .....


<edit> I just found the answer on 914rubber.com <edit>

You can read the rest for context but the above post has the answer.


While I was waiting for the new flasher relay to arrive, I decided to tackle the fog lights.

With the low beam lights on, when I pull out the fog light switch:
1. High beams switch on
2. High beam indicator comes on

With the high beams on, when I pull out the fog light switch:
1. High beams stay on
2. High beam indicator stays on

I measured the inputs and outputs of the fog light relay:

Pin 30 input power and shows 12 volts
Pin 86 receives power from the fog light switch (gray/red wire)

Here is where it gets weird:
Pin 87 is never energized, switch in or out (white/yellow to the fog lights)
Pin 87a is always energized, switch in or out (dead ended in the socket)

UNTIL I measure Pin 85! Once I put my multi-meter on pin 85 (with the fog light switch pulled out) I now get power (12 volts) on pin 87 (IMG:style_emoticons/default/confused24.gif) (and to the fog lights) and no power on Pin 87a (which is how it should be).

Pin 85 (8.5 volts) connects to the (white/blue) (high beam indicator, connects to the white wire at the fuse panel which feeds the combination relay and the headlights)

Still, pulling out the fog light switch always turns my high beams and the indicator on (instead of off).

27 is the combination relay
53 is the fog light relay
36 is the fog light switch


Power flows from the fog light switch (36) (grey/red) to pin 86 on the relay (53).
From there power flows to pin 85 (white/blue) which turns on the high beam indicator in the tachometer and connects to the white wire feeding the low beams and the combination relay (27)
From the combination relay it sends power to my high beams (yellow wire).

Is this an independent problem or something horrifically wrong with my wiring harness?

Thanks.
