12 Volt Ignition Help

[Drey]

I had a Tranny Temp Gauge wired up to the spot on my fusebox that has 12 volts with the ignition on.

At some point when I put my dash back together this afternoon it lost power, the spot beside it that has a pink wire with a black strip also doesnt have power now.

I checked the guage out with the spot to the left of the pink/black wire which has a constant 12 volts, and it kicks on then so at least I know the guage isnt bad.

My understanding of these panels are that the accessory terminals are fed through the circuit breakers. Later use two small silver breakers, they look like oversized metal fuses. You CAN put a fuse in their place to test.

Check other fuses though too. Only other thing I can think of is the ignition switch feed, but that's pretty unlikely, as is the wire coming off the back of the fuse panel falling off.

There is something right below it that looks like a fuse and says SHUNT I think on it. Is that it?

No, the shunts just let power through them...but they could also be a problem.

We're dealing with blade fuses, right?

You should see two silver colored oversized fuses, those are the circuit breakers I was talking about. Got a picture of your panel?

Yeah blade style fuses, 91 K5 no, im headin up to town now to get some fuses and ill see if they have some circuit breakers too

Just pull one of the other fuses in your panel and swap it with the shunts/breakers, or hit the shunts/breakers with a multimeter and see if they've got continuity. Neither go bad very often, as a matter of fact I've never heard of it here.

If you've got reason to go buy the stuff go for it, but don't just to try and fix this problem.

Well turns out Im an idiot. Apparently if the Ignition fuse is blown it takes out those spots for power...but the truck will still start. A breaker was 3.29 so I bought it for nothing, but im debating whether or not to take it back, could always use it for something else maybe.

 

[dyeager535]

I made the same mistake...was going to use a lower rated breaker for some of my injection stuff, decided it was a bad idea, so I've got a low amp breaker that's useless.

Eh I still have the OReillys receipt, I might take it back, I dont know yet. Should get a new O2 sensor for it anyway at some point.
