Alternator out put (B18c1)

What is the output of an alternator from a B18c1? Is it different from the ones on our B18a’s? I have a spare B18c1 laying around and my current alternator is “dying.” When i step on the brakes, my head lights dim. lol.

TIA

i dont have the exact number but it should be betweeen 13.5 to 14 volts when it’s charging. you’ll have to use a voltmeter to find out.
