It's time for me to switch the 58 GMC grain truck over to an alternator. It still has its 12 volt generator and Delco Remy regulator. The truck is all original but gets used so it needs an upgrade. Right now it's my water truck for remote stock tanks and I can't leave it idle with the lights on. The generator also needs a rebuild as it has an intermittent short and I'm not putting the money into it.
Anyway, I'm going to put a 10si on it. I don't want to cobble the wiring. Can I run a wire from the alternator over to where the regulator is and use it as a junction to the wiring loom? I was thinking about disconnecting the field and arm wires, leaving the "bat" wire attached to the regulator and putting the line from the alternator under the same screw with a crimp on spade. This way all of the wiring would be fed the same as it always has. My question is whether having only the battery terminal hooked up at the regulator could cause a parasitic draw?
I could run new wires but everything there is in good shape and functions correctly. I don't want to cobble up an otherwise original truck with 77,000 miles on it. Someday at my farm sale some nut like me could buy it and return it to original if I haven't gone through and cut up the original wiring connectors. When I switched one of my old tractors over I did something similar - I used the existing wiring to make all of the connections. I'm just not sure about using the battery terminal as a junction block if nothing else is hooked to the regulator.
