The ammeter is not an issue. No reason to dwell on it at this time. Waiting for voltage tests to get motor started. If we think it has anything to do with the ammeter, we will take it out of the circuit. You may be confusing the poster into thinking that we care about if the ammeter can handle the voltage/amperage/bowling balls. Lets have this discussion after we get the motor running.
When I said "provided ammeter can handle 12V system" I should have said "provided the ammeter can handle the alternator amperage and any added loads."
The voltage won't matter but the old ammeter shunt design/resistance may not protect the ammeter coil wires. Don't know. If the alternator supplies higher amps to a higher load demand, it could burn out the ammeter. But that still won't affect the circuit or starting.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
