Hello, I have been attempting to rewire a 1939 1.5 ton truck that was just recently given to me by my father. I have been using a kit I bought from Chevs of the 40's, it is for the original generator. The instructions are sort of vague and I am not sure where I am supposed to connect the big wire from the Ammeter to the generator, this was a fire truck for part of its life and it has what looks like a condenser for a radio on the generator. when I attached the wire to this, the ammeter read discharge even with the key off. There is what also looks like a voltage regulator on the firewall that the instructions do not mention. I have very little experience with wiring and the lack of color coordination or markings on gauges is really hampering my progress. Any help or tips are greatly appreciated.
