Levelers

My levelers would not retract this morning whe I was ready to leave. I call a Jayco technician and told him I turned the power on and than hit the retract button and it kept kicking off. He told me to try starting the engine wihic I did and it worked. He said the house battery is probably bad.

I then received a call back from a local mobile repair person and he to me it is probably the engine battery because most of the levelers are on the engine battery. But I’m thinking why did the engine start. a Also we notice the refrigerator light was dim all weekend which we were plugged into shore power.

Any thoughts on which battery it could be.

Thanks, Larry

I am pretty sure it is off the chassis battery. That is why engine must be running in order to use levelers or you get low battery if not running.

Ok, but why would the light be dim in the refrigerator also or just coincidence. The light maybe going out or loose connection.
I will be getting the batteries checked next weekend.

Don't quote me on this but I think your 'fridge is 12V. Yeah when plugged in, you should be getting a full 13.2V or better off the converter. But maybe this is an indication of a possible problem.

Yes the refrigerator is 12V, the refrigerator should be on the house battery and the jacks should be on the chassis battery, so does this mean both batteries are bad.

On a different note, I read on this forum you should start your engine when extending or retracting your leveling jacks. In the Jayco manual is says turn the engine off, what do most of you guys do.

Not sure what jacks you have (mine are Equalizer systems) but low voltage will not allow jacks to operate properly. I am dealing with that right now. In my case, it appears that my jacks are connected to the house battery and there is no requirement to have the engine running to extend or retract. However yours may be set up differently. Steps are certainly connected to the engine battery.

Even though your batter may have been low (check resting voltage with multi-meter), it may have been enough to start the engine. Another possible and common problem is a bad ground somewhere. If a ground is making poor contact, even slightly less voltage than normal can create problems.

If starting the engine resolved the issue, count your blessings. Mine appears to be the controller ($556 shipped) to fix the 3 year old ES jacks. I am not happy about it, but US built jacks does not necessarily mean US built electronics, so I guess I write the check and figure I saves another $500 by doing it myself.

Thanks for the response, yes I was happy when starting the engine solved the problem.

My rig is set up so the engine MUST be running to run the jacks. They use A LOT of juice, so it makes sense IMO.

I understand the chassis battery may be bad and causing the leveling jack problem..

I can’t understand why the frigid light was dim, I was plugged into shore power, I would thing the frigid would be on the Coach battery. Maybe both batteries are bad.

As with Camper Bob, in our 2018 29MV, the engine MUST be running and the emergency brake set before the jacks will deploy.
