STEP 8.
Measure the voltage on the end of the wire (A4-24+) with respect to A4-25.
0090), as necessary.
b. If harness is good and voltages are bad, check all GSC fuses (FO-4,
Sheets 3 and 5).
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 not 4 Vdc to 6 Vdc, repair or replace harness (WP 0043).
b. If voltages are good, replace LSM A4 (WP 0041).
c.
If harness is good and voltages are bad, replace GSC (WP 0040).
STEP 12.
Verify the problem has been resolved.
