Re: 56 Exec. Generator to Alternator

I did find out some info on the process from the company that sold me the alternator:

How do I wire an alternator in place of a generator?

Since not all vehicles are wired exactly the same the picture below is a simple example of the wiring requirements for installing an alternator in place of a generator system. Using the original generator regulator as a junction to connect all of the positive wires makes it simple. You may also route the wiring in any fashion you like as long as the power is distributed to both the battery and the vehicle's electrical components. The Armature and Field wires that were previously connected between your old generator and regulator can be removed and discarded. NOTE: The picture below is for negative ground systems. If you are connecting on a positive ground system then the cable at the battery will connect to the negative battery terminal.


One thing that was mentioned is that the original Amp gauge wouldn't handle the high amperage that the alternator puts out ( the gauge would 'fry'). The remedy was to create a 'secondary' path for the extra amps to travel, that is to use 10-gauge wire to bridge between the terminals of the Amp gauge.
