Place red lead of multimeter on male connector of wire J and black lead to ground. Turn MASTER
and APU GEN switches ON and check for voltage. Turn MASTER and APU GEN switches OFF. If
voltage is present, repair/replace wire J of bulkhead to APU, master relay, and rigger's lights wiring
harness (see WP 0225 00). If voltage is not present, repair/replace wire J of bulkhead to engine wiring
harness and starter relay wiring harness to bulkhead disconnect (see WP 0221 00).
22. Reconnect wire J to hydraulic pressure switch. Disconnect wire H from hydraulic pressure switch.
Place red lead of multimeter on wire H and black lead to ground. Turn MASTER and APU GEN
