1956 Power Hawk. Stock 12 V Gen charging system.
New wire harness
New Gen
New Volt reg
Dash is double grounded
Gen is grounded
Eng is grounded. ( grounds were tested) even though an AMP meter does not ground, we wanted to be sure everything else was good.
Had the Batt cable off several times. Polorized the Volt Reg each time to be sure.
Car runs and Batt tests 12.6 sitting starts and runs. Batt shows 14 V when car is running. Gen shows 14 Volts running tested at the Volt reg. Volt reg has a good ground. Car seems to be charging but not a blip on the Amp meter. Tested the big stud at the Starter Sol running and it shows 14. V . Following the circut, went to the AmP meter and saw 14 V running... The Amp meter will show a discharge when you turn on lights/ fan etc.
Tested the AMp meter by putting it between a battery and a slow batt charger. The meter shows about 6 amps.
Tested the wires involved and even at each 'lug' end at the key switch, Amp meter, volt reg and Gen.
Tested the Amp meter by switching the 'input' ( Red wire) with the 'output' (2 Black) wires. As expected, it read backwards. Only showing + when you turn on lights etc.
An Amp meter is measuring the load running through it and they seem to rarely fail. When I swapped it with another one I was amazed it did the same things.
What would make an AMP meter not show readings? Not enough Amps going into it ? (charge) I have 14 Volts, but no idea how many Amps.
