TROUBLE-SHOOTING TIPS
CONDITIONS:
With the RV engine “ON”
With the monitor switch “ON”
Towed vehicle connected to the motor home via the coiled cable
PROBLEM: Red light/alarm comes on and Pump is not running
1. Check the 10-amp fuse in the blue wire at the fuse holder in the blue wire.
2. Check the connection of the blue wire at the motor home battery.
3. Check for tight connections of the coiled cable at both motor home and towed vehicle
sockets.
4. Check with a continuity tester for power on the red wire at the socket of the motor home.
Continue with the socket on the front of the towed vehicle. There should be 12 – 14 volts
getting to the pump.
5. Call REMCO for more information.
PROBLEM: Red light/alarm comes on and Pump is running
1. Check transmission fluid level in towed vehicle. See vehicle manual.
2. Check for damage of the socket wiring and lube pump hoses from road hazards.
3. Use a test light to check power across both terminals of the pressure sensor at the selector
valve. If one has a 12 Volt DC Voltage Meter, then measured voltage should be the same
on both terminals, 12 – 14 volts. Trace the black wire to the monitor. There should be at
least 12 volts at the back of the monitor on both Red and Black wires.
4. Check the flow of the transmission fluid from the pump. The lube pump should pump a
quart of fluid in about 10 to 12 seconds. Check amperage on pump with an AMP meter.
With pump getting at least 12 volts of electricity it should be pulling between 2.0-3.5
Amps. Anything above or below that threshold means pump is going bad.
5. Check for grounding/shorting of the red wire of the 2-conductor cable running back from
the monitor to the socket of the motor home.
