Slides not opening or closing

Is it possible you overheated pump motor running them in and out and it needs to cool to reset??

Make sure your bay doors are completely closed.

I assume you have hydraulic slides? So I also assume you have a VOM? I also assume you actually used a meter on the fuse? But on most hydraulic pumps there is no fuse, but a resettable circuit breaker. Have you checked all of the breakers and reset them?

I have electric slides. but I suspect they have one thing in common.. interlocks and a locking safety switch.. My Key lock switch broke.

Under your steps is where you will find fuses for your hydraulic slides. Corrosion is a common problem also and there is a relay for the pump’s 12V motor...check it.

Found fuse for hydraulic
Pump under steps. Fuse checked out ok.can anyone tell me how to check the pumps relay?

You jump 12V from the large terminal (12V from the battery) to the small terminal of the solenoid using a short wire or a test lead from your VOM.

Try operating your leveling jacks. IF they operate the pump and relay is good. Doug

Our slide and levelers lost power a few days ago, as I ranted a few days ago, both the manufacturer and the mobile tech we called suggested upgrading at a cost of $1400+shipping and labor.

HWH didn't make the motor and doesn't stock it, because the upgrade calls for replacing not only the motor, it calls for a new pump, reserviour and solenoids.

Google search turned up several motors for $95 to $129, tech said "if it doesn't come from one of our suppliers, we can't guarantee the motor is correct replacement.

Replacing is a 1 hour job, upgrade is a 3 to 4 hour job and gives the tech a CYA out if the part fails.

It pays to be flexible and to learn how to fix your equipment.

Bad ground?
