Hello. As I was attaching me new wiring harness to my '37 120C,, I was doing it one bit at at time. I had the generator and voltage regulator hooked up along with the starter solenoid. I connected the battery to see if anything might be amiss and all appeared well. after disconnecting the battery, I connected the ammeter over to the ignition switch as shown in the diagram I received from the company who made the harness. When I then connected the battery, smoke appeared from the dashboard and by the time I was able to disconnect the battery, I had completely fried the line from the ammeter to the ignition switch. I took my voltmeter and determined that there was live current from both sides of the ammeter. Do you know if that would indicate a short in the ammeter, or should I be looking somewhere else? There is definitely a short in there somewhere, but all of my information that I have on detecting shorts only works on modern cars based checking the amp draw based on fuses.
Thanks as usual for any information you might be able to give.

The ammeter is a "pass thru", you should be live at both sides. Perhaps a short in the ignition switch? Or if there are further connections from the switch, then perhaps a short there.

Thanks. I was wondering about that for my ammeter is live on both sides. I just had the ignition switch reworked, but I'll see about detecting a short there. I know I do have good current when the switch is turned off and nothing when it is turned on, so that does remain an enigma to me.
Thanks, again.
