SIMPLE fix just became COMPLICATED...

2006 Mandolay Valencia with 10,000 miles on her; we are second owners and have had it one month, two trips and 1700 miles. So far so good, or so we thought.

One week between first and second trip, so jacks stayed UP and slides stayed IN. Ours is an Equalizer system that uses one hydraulic pump for both jacks and slides.

Morning of our second trip and neither jacks nor slides would work. Keypad for jacks showed an, "all jacks are not up", message (along with the warning buzzer). Disconnect wiring harness to keypad and do the trip.

Get home and contact Equalizer. Seems that shorting the solenoid didn't produce any life into the pump motor, so it must be defective. Order motor.

Installed new motor and rear slide worked fine. Front slide hung up on the front, so a few times In and Out, trying to get the slide to open evenly. No luck, so I went inside to cool off. Came out 30 minutes later and...and no life at all on the new motor

Coach is like new, with no rust or corrosion anywhere (Missouri)


What could possibly cause the new replacement motor to work only a few minutes? Also, could the un-even slide extension be related, or a symptom of a different problem? All suggestions welcomed by this newbie

Check for a tripped DC circuit breaker on or near the 12vdc board, but then it should have remained tripped from the last one. There might also be an auto reset type breaker and/or and internal thermo overload, but, they should've reset themselves, so just consider some of this, food for thought, while disconnecting it for a spell and then reconnecting it. Another approach would be to run a temporary lead out on the ground and to the pump motor from the coach batteries and see what that might do and I guess you've already tried that once. If you still have the old motor, try bench testing it or out of the coach, anyway and make sure of a good ground return.
