i have a 12 alt on my 1972 commando 258 inline six...can anyone tell me what i need to hook the wires up too to get it working properly. i had someone rebuild the engine and they did no hook it up correctly and it is not charging the battery...
 
ok, check out the pic post #9 in this thread. is this what the back of your gm alternator looks like? if so if you read a couple posts down i outlined how mine is wired up on my 350.
