69 turn signal signal question

[MorePwr]

I heard the flasher clicking yesterday, with the signal switch in the off position, key on, got out and checked the lights...nothing blinking..proceded to check all the lights, everything is operating correctly.

other than a melted wire letting power bleed over to the flasher, which is all I can think of. Has anybody seen a bad switch do this?

Any suggestions?

there are 2 flashers 1 for turn &  1 for hazzard lights , it could also be a relay for something clicking on & off , can you pin point where the sound is coming from better?

It's definitely the turn flasher, I held it in my hand and can feel it clicking, softer though, and not as regular as when the signals are on, it skips a beat now and then.

I'll get under there and check the voltage and look for melted wiring?

somethng is putting a load on that circuit

I agree. I'm gonna pull the guage panel today to access the wiring. yesterday I tested the two wires for the flasher and found that the black one had a strong steady 12 volts with the key on and switch off. I also discovered a burn mark on one of the flasher posts. I'm guessing that the way I tucked the flasher back up under the dash, let it rest up against the bottom lip of the dash board causing the opportunity for a short.  Also saw a spark and smoke when I turned the emergency flashers on.....yup , battery's disconnected now. Now begins the search for the melted wire.

Flashers have an input an output.
Hazzards for example has black and pink wires where black is constant input, and when steering column hazzard switch ( since 70 ) or hazzard cluster switch ( 69 and earliers ) routes the power to 4 corners, then the bulbs load is what makes flasher works, cutting power when bimettalic stuff inside flasher heats for load. Then gets cold, and close circuit again until heats and cut.

Is very tipical get burned plugs to hazzards WHEN YOU USE AN INCORRECT flasher to that kind of load. Really needs a heavy duty flasher.

turning signals are the same with just change on wires codes and power is get on key Run position... Red and black

Great info, thanks! that would explain why the flasher is clicking all by itself. I'll go buy a heavy duty model and see if that fixes that issue, still gonna have to find where the spark came from though.

Update

I replaced the flasher with a heavy duty one. no luck. I did find the culprit though..Apparently 15 years ago when I had the column out, I wasn't carefull enough with the routing of the ribbon wire for the signals and got it pinched. oops! atleast I found it before it had a meltdown.

AT least you found it !!
