Shut down ROWPU. Refer to TM 10-4610-239-10. Shut down power. Refer to
circuits between junction box ground terminal El and K6 terminals T1, T2, and
T3.
If any terminal is shorted to ground terminal E1, go to step 8.
If no terminal is shorted to ground terminal E1 replace K2. Refer to
Step 8.
Remove booster pump cable assembly. Refer to paragraph 3-31. Refer to
schematic diagram figure FO-3. Check for short circuits between wire lugs on

Step 9.
Shut down ROWPU. Refer to TM 10-4610-239-10. Shut down power. Refer to
generator manual. Remove booster pump cable assembly from motor. Refer to
end of cable.
If any measurement does not indicate continuity, repair booster pump
cable assembly. Refer to paragraph 3-17.
If all three measurements indicate continuity, repair booster pump
electric motor. Refer to paragraph 3-29 or 3-30.
Step 10.
Shut down ROWPU. Refer to TM 10-4610-239-10. Shut down power. Refer to
continuity between K6 terminals L1, L2, and L3 and J1 pins A, B, and C
respectively.
If all three measurements do not indicate continuity,, go to step 11.
If all three measurements indicate continuity, repair K6. Refer to
