Step 12.
Remove receptacle connector J6 from electrical junction box. Refer to paragraph 3-36.
Refer to schematic diagram figure FO-3. Check for a short circuit between J6-D and K1
terminals T1, T2, and T3.
If any terminal is shorted to J6-D, repair cable W:10. Refer to paragraph 3-17.
If no terminal is shorted to J6-D, replace J6. Refer to paragraph 3-37.
Step 13.
Remove R.O. pump motor cable assembly. Refer to paragraph 2-121. Refer toschematic
diagram figure FO-3. Check for short circuits between P6-D and P6-A, P6-B, and P6-C.
If any pin is shorted to P6-D, repair R.O. pump motor cable assembly.
Refer to paragraph 3-17.
If no pin is shorted to P6-D, repair R.O. pump electric motor. Refer to
Step 14.
Shut down ROWPU. Refer to TM 10-4610-239-10. Shut down power. Refer to generator
manual. Refer to interconnect diagram figure FO-4. Check continuity between K1 terminals
L1, L2, and L3 and J1 pinsA, B, and C respectively.
If all three measurements do not indicate continuity, go to step 20.
If all three measurements indicate continuity, repair K1. Refer to paragraph 3-47.
Step 15.
Shut down ROWPU. Refer to TM 10-4610-239-10. Shut down power. Refer to generator
manual. Remove R.O. pump cable assembly from motor. Refer to paragraph 2-124. Leave
cable connected to J6. Refer to schematic diagram figure FO-3. Check continuity between
K1 terminals T1, T2, and T3 and wire lugs on end ofcable.
If all three measurements do not indicate continuity, go to step 16.
If all three measurements indicate continuity, go to step 17.
