can someone give any advice on how to wire up an alternator correctly. i just want to make sure i have it right next time before i burn out another one. i am using a mid eighties tpi alternator on my lt1 for packaging reasons, it is a lot smaller. i wired it the same way the lt1 alt was wired (only "L" wire from the connector was used on the lt1) this wire is the ignition on 12v source to get the alt charging. and then of course the power supply from the back of the alt to the batt. the tpi alt harness connector has wires in the "S" "F" and "L" location in the connector. i am thinking i may need to connect the S wire(heavier gauge red wire) also to a switched 12v source but not sure. also will not having any of these wires hooked up burn up the alternator? both of the alt i had would charge good the first time or two i cranked it but then would stop after no more than 5 minutes of run time.
