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

We have run into this on the 5th wheel slides by having a weak 12VDC battery in the system. Sometimes the DC OUTPUT of the converter needs a little more boost from the trailer 12VDC battery to work good.

We have actually nosed the truck up to the battery bank a couple of times and used the truck jumper cable to help out...

Sorry about the problems you're having, almost right out of the gate. That always makes us second guess our decisions, but hang in there.

There are several issues that concern me. If the slide is hanging up in the front, I would look into that, and find out what is causing it. I'm not familiar with your rig's system, but there are usually glides of some sort, that the weight of the slide, slides on. Is one broken or missing? Is there something that has changed with alignment of the slide in the wall?

Have you checked for full voltage at the pump motor, while someone operates the controls? I haven't heard of a pump motor burning out, so 2 in a row for you, seems very odd. Could it be a control relay, or bad connection in the electrical system for the pump? Have you tried running the motor (either the old one or new), directly from a 12v battery? I would check these things first.

BTW, do you happen to be a member of a certain boating forum? We have a member there with a very similar screen name, who I think I remember saying recently bought an RV. Hope we can get thing figured out quick. Maybe a call to "Equalizer" customer support may help.
