Step 7.
Shut down ROWPU. Refer to TM 10-4610-239-10. Shut down power. R fer
e
to generator manual. Refer to schematic diagram figure FO-3. Check for short
circuits between junction box ground terminal El and K5 terminals T1, T2, and
T3.
If any K5 terminal is shorted to ground terminal El, go to step 8.
If no K5 terminal is shorted to ground terminal El, replace K5. Refer to
Step 8.
Disconnect distribution pump cable connector P5 from ROWPU. Refer to
schematic diagram figure FO-3. Check for short circuits between P5-D and
P5-A, P5-B, and P5-C.
If no pin is shorted to P5-D, go to step 9.
If any pin is shorted to P5-D, go to step 10.
Step 9.
Remove receptacle connector J5 from electrical junction box. Refer to
circuit between J5-D and K5 terminals T1, T2, and T3.
If any terminal is shorted to J5-D, repair cable W9. Refer to paragraph
If no terminal is shorted to J5-D, replace receptacle connector J5. Refer
Step 10.
Remove distribution pump cable assembly. Refer to paragraph 3-25. Refer to
schematic diagram figure FO-3. Check for short circuits between P5-D and
P5-A, P5-B, and P5-C.
If any pin is shorted to P5-D, repair distribution pump cable assembly.
Refer to paragraph 3-17.
If no pin is shorted to P5-D, repair distribution pump electric motor.
Refer to paragraph 3-29 or 3-30.
