1980 Charging System Problem
Battery is discharging.With engine running,only reading about 13 volts on car's voltmeter gauge which agrees with the reading from a voltmeter hooked up to the battery.At the alternator is where the readings are very unusual.The small brown exciter wire has 1.5 volts with the key on engine off and 30 volts with engine running.The red wire at the plug has 13.1 volts both KOEO and KOER. The red output wire shows overcharging with 177 volts.Could this be a problem with the ignition switch or the dash printed circuit? (battery is fairly new with clean connections,alternator is new,cleaned chassis grounds)
