I was think of making a voltage divide to reduce the voltage. Say use a 30 ohm and a 10 ohm resistor. The divider would draw a little over 1 amp and I have power resistors that can handle that.
Problem, if we use a delco with a built in VR, where is the input to the VR? Are the two smaller wires on the alternator the input to the Voltage Reg? The one right goes directly to the +12v and the one on the left goes to the idiot light or to a diode?
So instead of giving the alternator full 12v on the right wire, run it to the voltage divider and give it 1/4 the volts? However the out wire of the alternator will be connected to 48 volts, so the voltage divider will still provide 12v. Do I have it right?
You mention something about watching the ma. Educate me, what are you talking about?
I think you send me a diagram, how to wire up a Massey generator, which by the way, I got working for a friend, Thanks.
Got a diagram of the delco alternator? Don"t really care which delco. Friend will want the one that has the largest amp rating.
