Enos blackbox is simply a circuit breakerboard made up for streetrods- make the wiring simple and neat.
If I check Amperage at the alternator- it will be 20 when I start the motor. If I check voltage- its 17 volts when motor start which then falls to 15 volts- still plenty to cook a radio. Yes single wire GM alternator- motor starts and battery remains well charged. VOM meter is OK.
