P8 Wring Harness Testing. Wiring harness P8 runs from connector J9 on contactor K2 to terminal
board TB1.
(1)
Set multimeter controls for continuity testing.
(2)
Touch one multimeter test probe to connector P8 contact A and touch remaining test probe to
TB1 contact 13. Multimeter must indicate continuity. If it doesn't, there is an open in connector
or wire.
