I have a 98 Seville STS with the Service Charging System, ran the codes and I am getting P1638 Generator F Circuit. I changed the alternator twice and the battery a couple of times. Changed the negative battery terminal. I did see that the positive battery cable has a connector that was broken(the two wires coming off of it), I cut that out and hard wired the wires together with butt connectors still same issue....did anyone else have this issue or can help me out, would be much appreciated.
Thanks
Frank
