Stovebolt Brethren, as far as I'm concerned anything electrical is black magic so I've got my hands full installing a new harness in my '58 GMC.
The harness I bought is a copy of the original with the exception that it set up for an alternator instead of a generator. The problem is the harness is for a Chevy which has an Ammeter. My GMC just has a generator idiot light so I need to know how to wire the generator light and eliminate the ammeter circuit.
Please try to keep your responses to about a 2nd grade level and step by step if you would be so kind. I'm new at this electricity thing.
