A call for help to the electrical specialists.

@ Brent
Hi, thanks for the quick reply.
When I bought the Ford, the ammeter already stopped working, I thought the ammeter was disconnected during the conversion to 12 volt. I haven't driven that much yet, I've repaired the other things first.
The alternator has an internal regulator, the alternator is also earthed.
I couldn't read the ignition timing with my digital ignition gun because the value was always jumping around.
Is there a wiring diagram for the wiring to 12 volts for the Model A? Something like that would help me a lot!
Can I also operate the original ammeter with the 12 volts or will it break?
Is it really possible that the ignition system does not allow measuring with digital measuring instruments? Like Bob C writes?

Thank you very much in advance

Joe
