1. Stop engine (see your -10).
2. Install regulator on regulator plate.
3. Install front main wiring harness plug C4 on regulator.
4. Remove engine harness plug (1) from generator field
switch jack (2).
5. Install jumper (3) on engine harness plug (1) between
pins NO (4) and C (5).
6. Turn MASTER SWITCH to ON.
7. Measure voltage between front main wiring harness
plug C5 (6), socket F (7), and ground.
8. Does multimeter read less than 17 volts?
1. Turn MASTER SWITCH to OFF.
2. Remove engine wiring harness plug C7 (1) from front
main wiring harness bulkhead jack C7 (2).
3. Measure resistancebetween C7 plug (1), pins B (3),
and F (4).
4. Does multimeter read 0 ohms?
1. Replace generator field
switch (page 9-44).
2. Verity no faults found.
1. Remove jumper wire from
generator field switch plug.
2. Measure resistancebetween
plug C7, pin B, and engine
harness plug pin NO. If
multimeter reads 0 ohms,
see step 4.
3. Measure resistance between
plug C7, pin F, and engine
harness plug pin C. If
multimeter reads 0 ohms,
see step 4.
4. Repair engine wiring harness
