is one that covers lighting for an AD truck........It was made by a user here (Chief? someone correct me if I am wrong).
I still had it on my website, or it would have been lost.
On my Dad's '57 3600, we used an SI 10 Alternator, no need to fool around with all those wires. We did use an "Idiot" light on a harness we made ourselves.
Without the light, the truck would not turn off.
Ammeter still worked, no re-wiring required.
Beat the heck out of a Generator, especially on a 283.
I am sure better answers will come along shortly.
I am a "jack-of-all-trades", but Master of NONE!
