STEP 8.
Measure the voltage on the end of the wire (A4-24+) with respect to A4-25.
0088), as necessary.
b. If harness is good continue to the next step.
STEP 9.
Adjust the engine speed so the frequency is 1 Hz lower than what is on the load
bus.
STEP 10.
Allow voltage to stabilize.
STEP 11.
Measure voltage on the end of the wire (A4-24+) with respect to A4-25.
a. If voltage is not 4 Vdc to 6 Vdc, repair or replace harness (WP 0044).
b. If voltages are good, replace LSM A4 (WP 0042).
c.
If harness is good and voltages are bad, check all GSC fuses (FO-4,
Sheets 3 and 5).
d. If GSC fuses are ok, replace GSC (WP 0041).
STEP 12.
Verify the problem has been resolved.
