Generator To Alternator Wiring Diagram Mg

Alternators usually have internal voltage regulators.
Generator to alternator wiring diagram mg. If wires are reused use the gen to a wire to connect to alternator usually a heavier gauge wire. Wiring cut a plug from a gm car in the bone yard. The challenge for many of us is how to wire the upgrade. As you can see the bat post of the regulator is being used as a junction point for the battery connection to the new single wire alternator.
Oh you did notice that extra optional wire in the last diagram. Installing an alternator in place of a generator or upgrading an older style alternator to a more modern alternator is usually not hard to do. Dave 71 and 72 are the same so don t worry. Remove all the wires from the control box as show in figure 9b.
Attempting to pump 40 amps or more through the original 12 awg charging wire is not such a good thing. The field wire has been removed taped off and is no longer used. The small brown wire goes to the 2 terminal field of the alt plug. On mine it is a 14ga red wire the small brown wire with yellow tracer goes to the 1 terminal indicator of the.
Attach it to the bat connection on back of the alt. Figure 9a below shows a stock negative ground vehicle s wiring diagram with the generator still intact. Generators had external voltage regulators. Figure 9a figure 9b.
The alternator is internally regulated and no longer needs the external generator control box voltage regulator.
