If you have a 12V test light or volt meter you can do some simple checks:
1. With the Ign off check for power at the Alt B+ wire (BK/OG wire). If not, check for open circuit or blown fusible link between the Battery and Alt.
2. With the Ign off unplug the wiring connector at the Alt and back probe pin 1 (YE/WH wire). There should be power. If not, check for open circuit or blown fusible link between the Battery and Pin 1.
3. Turn Ign on and check for power on Pin 3 (LG/RD). There should be power with the Ign on. If not check for a bad fuse in CJB.
If all these check good, then either somethings wrong at the plug and one of the wires are not making a good connection or you got a bad alt from Kragen's.
