If the fuse had failed:
A. Check the weather packing of the power connector to the ABS module C104b (Motorhome C1047).
B. Remove power distribution box fuse 14 (60A) (Motorhome fuse F [60A]).
C. Measure the resistance between the outside pin of power distribution box fuse 14 (60A) (Motorhome fuse F [60A]), circuit 532 (OG/YE), and ground.
D. Spray with water and wiggle the wiring between the power distribution box and the ABS module.
E. If any continuity is measured, repair or replace the wiring.

Check for opens in wiring:
A. Disconnect ABS C104b (Excursion C104).
B. While measuring the voltage between ABS C104b-2 (Excursion C104-2), circuit 532 (OG/YE), and negative battery post, wiggle the wiring harness.
C. If the voltage momentary drops below 10 volts while the harness is wiggled, repair or replace the wiring.
D. While measuring the resistance between the ABS C104b-1 (Excursion C104-1), circuit 530 (LG/YE), and ground, wiggle the wiring harness.
E. If the resistance momentarily goes above 5 ohms, while the harness is wiggled, repair or replace the wiring.
