WHY AM I NOT CHARGING?!?!?!?!?!

I have a 1g alt, stock ignition switch has a wire running from it, to a splice into a wire that runs from the instrument panel to the I post on the voltage regulator.

Was told to hook up the exciter wire in the kit I have, in place of this. The truck cranks, but does NOT charge. I think this wire originally was a resistive wire, but i'm not exactly sure. All the diagrams show a "dummy light" in line with this wire, but I don't have one anymore, and don't believe I did in the beginning as I have full gauges, not just lights.

Is it safe to run without a light, and just run a wire straight from the switch to the regulator?

**edit**Okay, I wired that wire up directly from the switch to the regulator and still didnt see 13.5...I had the alt tested, battery tested, and all cables are new grounding and power wise, as is the wiring harnes

try a new ground! i had that problem with my motor bike

I honestly don't know where I would ground....I guess I'll try and somewhere

usually the ground runs from the end of one of the cylinder heads over to the battery

ive got one from battery to alt bracket bolt (couldnt find the hold on the head, checked for it already),from motor to firewall, and firewall to frame.

that help?

i swaped to a 2 g alt. on mine cuz the voltage regulator is a pile of shit. mite be worth sumthin lookin into.

id check the ohmage of the instrument cluster if its not that, u can always bypass it.

did you ground the alternator? i know i did mine one time, and it wouldnt charge ,it was self grounding to the bracket and didnt need an external ground.

yah, its grounded from the ground post on the alt to the regulator, and theres a ground running to the alt bracket as well. it was grounded to the firewall when i got it though.
