Hydraulic Levelers quit working

[FlyPatch]

I have a 2010 Montana 3400RL 5th wheel and the hydraulic levelers quit working. It happened last week when we got the mandatory Black Forest Colorado evac order. Bad timing to have them go out. We made it ok...good thing for manual cranks.

Synopsis:

I'm on shore-power, I checked fuses & breakers in the electrical panel (all appear good). My 12V dual batteries are online and good. My hydraulic fluid is good. When I depress the retract/extend switches....nothing. It was suggested there might be an inline fuse located in the belly storage area, but I couldn't find anything. Doesn't appear to be any inline fuses in the battery compartment with the hydraulic motor.

Anything come to mind?

Does the leveler panel have power? You kinda say switch so not sure if you talking about landing gear or you have a full leveling system.

If you can get to the motor I'd check for power with a volt meter. Then after that the switch. Then before switch. Somewhere you'll have power before, but not after. If you have power all the way to motor to motor is bad. If at switch, but not motor then switch is bad. You get the idea. (Ensure switch is depressed while testing anything after switch)

Basic troubleshooting rule for systems is to start at the electrical load (motor) and work backwards to power source (battery). Any fuse will be between batt and panel. This is almost certainly the issue. A couple of my in line fuses where bundled and zip tied with other wires so really look it over in the belly storage.

If you trace the system from end to beginning you'll find it. Good luck.

If they can also be actuated by the remote control, you may need to retract them with the remote before the manual switch will work. On Cougars, it's that way. "What is done by the remote must be undone by the remote" What is done manually must be undone manually"
