If the alternator is functioning properly you should read somewhere around 13.5 to 15.5 volts DC at the battery with the engine running at idle.
It can put out too many volts and destroy the battery but not drain it. The alternator should put out between 13.5 to 16 volts.
From 13.5 to 15.5 Volts.
if the alternator is working properly it should always put out between 13 and 15 volts
13.5 to 16 volts DC.
around 14-14.5 volts
13.6 to 14.5 volts with all accessories turned on, depending on temperature.
30-35volts at 4500 rpm
With the engine running and all lights and acces off approx 14 volts should be put out
It should put of 13.5 to 15.5 volts. The alternator is an 80 amp alternator.
My understanding is that it takes about 20,000 volts to arc between the two parts of the spark plug and most automotive coil put out 20,000-50,000 volts.
13.5 - 14.5
12 volts DC.
