Well, back read everything.....I am bypassing the AMP meter in my 66. It is easy to do.....Al least if you understand wiring.....Keeps the high Amp circuit in the engine bay only. NOT thru the bulkhead connector. Installing a volt meter.....
I have always preferred voltmeters.
Key on, 12 volts or better-check
Cranking voltage no less than 10-check
Running voltage 13.2 to 14.6-check.
I just tested my battery,starter and alternator. What more can you ask for?
