[6pack] Electrical problems

[DAVID MASSEY]

 Thanks for the reminder about this collection of schematics.  I've had these for many years and I have referred to them on many occasions.  Kudos to Dan Masters who put a lot of time in research and drawing these up.
The Purple wire feeds the horns and the Flash-to-Pass function but the main power for the headlights comes directly from the power tap on the battery cable so unless you are driving around holding the Flash-to-Pass I am at a loss to explain a direct interconnection.  A dodgy connection in the fuse block could be the cause if it were otherwise.  Something to look for is a wire-to-wire short in the harnesses that lead down from the steering wheel.

Did you or anyone else do some work under the dash and disconnect and reconnect wires?

I'm no electrician, but have had pretty good luck. Looking at the purple circuit on a 76, it does seem there's a connection with the horn and the flash-to-pass switch. Could it be your horn relay is going bad, and sending negative back up thru the purple wire, and it's making its way over to the flash-to-pass/dimmer switch, causing your lights to blink? Do they blink 'on' or 'off', and does the horn also blow? 
Be aware that the headlight circuit is not fused or even protected by a circuit breaker, so  you could be treading in dangerous waters. You'll see the brown wires are a direct connection between the battery and the headlight switch, and also provide the 12v power to the purple circuit which is the 'always' on fuse (horn, glove box, hazard flashers).  So this is all definitely related.

Sorry I was not too specific on describing my problem.  It is the headlights that blink when I press the horn button.  I've had the car for 18 years,  daily driver, never had an electrical issue until now,  other than a badstarter and alternator.
