Customer Question

I have a 1950 chevy sedan delivery. I just bought it. They had a blaupunkt stereo in it but it was not wired. They left one of the 12v connections not connected when I hooked it up I found out why they left it disconnected. It worked fine when I hooked it up but as soon as I pressed the throttle pedal it cut out. So I found I am getting 18 volts at idle but 20 volts with higher rpm. Does this have to do with malfunctioning regulator or alternator?

need more information of Year, Engine & Charging Circuit
IF the increase in Idle raises the Voltage to 20 Volts, it likely is the Voltage Regulator "IF" it has one
Charging should be limited to below 15 Volts
