- replace the STAT INV (3XB) (Ref. AMM TASK 24-28-51-000-001) and (Ref. AMM TASK 24-28-51-400-001).
(b) If the voltage is less than 22VDC:
- replace the BAT-1 (2PB1) and BAT-2 (2PB2) (Ref. AMM TASK 24-38-51-000-001) and (Ref. AMM TASK 24-38-51-400-001).
C. If the test shows the frequency indication in amber:
- replace the STAT INV (3XB) (Ref. AMM TASK 24-28-51-000-001) and (Ref. AMM TASK 24-28-51-400-001).
D. If the test shows that amber crosses replace the voltage and frequency indications:
- do a check of the status of the circuit breaker (27WV).
(1) If the circuit breaker is closed:
- do a check for 115VAC at the pin 2 of the circuit breaker (27WV).
(a) If there is 115VAC:
- do a check and repair the wiring between: . the pin 2 of the circuit breaker (27WV) and the first branch point, . the branch point and the pins AE/8B of the SDAC 1 (1WV1) and the SDAC 2 (1WV2) (Ref. ASM 24-24/02).
(b) If there is no 115VAC:
- do a check and repair the wiring between the pin 1 of the circuit breaker (27WV) and the pin 1 of the circuit breaker AC ESS/BUS/EMER CNTOR/SPLY (15PC) (Ref. ASM 24-35/01).

(2) If the circuit breaker is open:
- close it.
(a) Do a check of the wiring for a short to ground between the pin 2 of the circuit breaker (27WV) and the first branch point (Ref. ASM 24-24/02).
1 If the wiring is not correct:
_
- repair it.
2 If the wiring is correct:
_
- replace the C/B-EMER/GEN/REF (27WV). R E. Do the test given in para. 3.
