Default Alternator questions...

i have a full custom autometer cluster, how do i hook up the alternator to work? more specifically the charge light. can i just hook up a LED/bulb to fool it?

i did some searching in this subforum for alts or maybe it was when i was searching for instrument cluster swaps and there is some good info on people swapping to autometers with the stock wiring.

me and luke think its the exciter wire. i bought some 470 ohm resistors(speartech recommends 470-500ohm) today so ill try them. since i pulled the cluster i think that "circuit" is broken so the alt wont charge, running my battery dead quickly.

Depending on the year, most LS1 PCMs manage the alternator directly...no bulb or resistor required.

My 2001 is this way, the alt's L terminal goes straight to the PCM.
