B. Check for Short Circuit at the ACTUATOR-AIR INLET FLAP (28HH) and ACTUATOR-AIR OUTLET FLAP (29HH) 115VAC Supply Lines
(1) Remove the CONTROLLER-PACK 2 TEMP (27HH)
(Ref. AMM TASK 21-61-34-000-001):
- at the electrical connector (27HH/AB) do a check for a short circuit between,
* pins 15A and 14B and,
* GND and pins 15A and 14B,
- at the electrical connector (27HH/AA) do a check for a short circuit between,
* pins 4B and 4C and,
* GND and pins 4B and 4C.
(a) If there is no short circuit install the CONTROLLER-PACK 2 TEMP (27HH) (Ref. AMM TASK 21-61-34-400-001).

(b) If there is a short circuit at the connector (27HH/AB) disconnect the electrical connector (28HH/A) from the ACTUATOR-AIR INLET FLAP (28HH):
- at the electrical connector (28HH/A) do a check for a short circuit between,
* pins J and N and,
* GND and pins J and N,
- if there is a short circuit repair the related wiring between,
* connector (28HH/A) pin J and PC connector (27HH/AB) pin 15A,
* connector (28HH/A) pin N and PC connector (27HH/AB) pin 14B.
- if there is no short circuit in the wiring replace the ACTUATOR-AIR INLET FLAP (28HH) (Ref. AMM TASK 21-61-51-000-001) and, (Ref. AMM TASK 21-61-51-400-001).
(c) If there is a short circuit at the electrical connector (27HH/AA) disconnect the electrical connector (29HH/A) from the ACTUATOR-AIR OUTLET FLAP (29HH):
- at the electrical connector (29HH/A) do a check for a short circuit between,
* pins J and N and,
* GND and pins J and N,
- if there is a short circuit repair the related wiring between,
* connector (29HH/A) pin J and PC connector (27HH/AA) pin 4B,
* connector (29HH/A) pin N and PC connector (27HH/AA) pin 4C.
- if there is no short circuit in the wiring replace the ACTUATOR-AIR OUTLET FLAP (29HH) (Ref. AMM TASK 21-61-52-000-001) and, (Ref. AMM TASK 21-61-52-400-001).
- install the CONTROLLER-PACK 2 TEMP (27HH) (Ref. AMM TASK 21-61-34-400-001).
