Maybe P1637???
Generator 2 L-Terminal Circuit
Has something to do with the little wire on the back of the alternator. I get that code all of the time and don't know why.

it comes up as 637, but that makes sense, because my friend just swapped his alternator because he forgot to plug that it. that is a fast way to waste 160.00 bucks.
