78 power wagon, no fuel gauge, no turn signals....

I think I know the answer, but I wanted to check


The gauges are dead, and to turn signals also and last time I remember the relay in the dash is he culprit. This truck it will come and go though.

Totally random ill get the gauge back then things work. Am I thinking correctly?

I'm looking at a 77 electrical schematic and I don't know what relay you are talking about, I don't see one. If you mean the little voltage regulator that only looks to affect the fuel, temp and oil pressure gauges. I don't see where there is any connection to it and the turn signals.

^ yeah
gauges in my truck don't work (it has mechanical ones added), pretty sure the voltage reg is the problem.
my turn signals still work...

I wonder if your turn signal indicators being inop are merely a coincidence? Those go out a lot on older Mopars because of the sockets or the circuit boards and a poor contact between the two.

You're talking about this I guess. Part #3592899

This may be a more accurate pic

I have about the same thing , with my 76 Trailduster. I was wondering it had something to do with the steering column wiring harness , turn signal and such.

No because that wiring wouldn't effect gauges. Or do you mean JUST your turn signal indicators? If just signal indicators, I'd bet just your bulb sockets/circuit board connection or bulbs themselves.

Turn signals , gas gauge and seems like some other things not working. The Trailduster is not running at this time , or I would check it more closely. ( it has fuel line and carb problems from sitting a while )
