3 wire alternator connect

[James G.]

What ohm value resister replaces the indicator light? I don't want to use the light.
Thanks

The Delco manual calls out a 10 Ohm 6 watt resistor for bench testing without a bulb.

you can also use a 1N5404 diode in line with the wire and have the white band towards the alternator.

I appreciate your help.
Safe and happy Model A windshield time!

James G send me an email and will send you the directions to add the diode to the alternator for the three wire setup. [email protected]

Is this for the positive ground system?

With the diode in that direction, it would be for negative grd system. In order for a diode to conduct, positive is on the non-striped side (anode). In this instance, the non-striped (anode) end of the diode goes to ignition. Striped (cathode) goes to alternator. This allows current to flow FROM the ignition TO the alternator. Caution: Reversing just this one diode will not make this a positive ground alternator.
