Tripac APU "Pre Evolution"

There's nothing on the alternator that would affect the fuel shutoff solenoid. You have a main feed to the starter, a feed to the logic board, a sense feed to the regulator and an exciter wire for the field.

When you hear the fuel pump come on test for voltage at 8SD. It will cycle to the pull winding fairly quick so it be best to have the probes already hooked up before hand.

You did remember to reconnect the ground wire to the alternator after replacing it didn't you?
