100 amp Bussman Breaker

[Mkayers]

Stupid question but I haven't been able to locate it. Do all coaches have the 100 amp Bussman breaker? It's not in my battery bay & I've crawled under and checked the frame rail & can't see it. Not sure where else to look. Having the dreaded Lippert "jacks down" error and can't get it to quit. Thought I would start by checking this. Thanks!

I'd skip that search for now and determine if you have 12+ VDC to the hydraulic leveling motor activation solenoid.

If so - see if the solenoid works and sends power to the motor.
If not - go back to your search for that breaker - it also supplies starting current/voltage for your generator.

This one is in the extreme upper left corner of the battery box under the floor.

[Mkayers]

Thanks for the hints, I guess it's probably not that because I can start the generator from the cockpit. I'll check the solenoid first.

Do a reset on the lci panel.
Should clear the jacks down error code.

Tried that multiple times and no such luck. Did top off the fluid also. I'm not hearing anything at the pump (but my ears aren't the best anymore lol, too much rock & roll )

Marty,
The is a fuse, 15 amp? Near the pump.
Thor resource owners page should help you locate it.
The panel is getting power from the board, located who nows were, but you might not be sending power to the pump. My controller was next to my inverter.

If you have a ford chassis, look in the fuse book, a 5 amp fuse runs power out there also. Can’t remember but I think its #10 or #11 on mine.

The "jacks down" on ours was a failed pump motor. The seal betwixt the motor and pump seeped fluid into the motor and it finally failed... a good cleaning and drilling a small hole in the motor to let future seepage out has cured it.
The beeping is letting you know there is no pressure holding the jacks up, they may be up as in my case and I disconnected the panel for a quiet ride home. Jacks never did inch down.
So it could be the pump motor, pump solenoid, pressure switch... start with those.

Thanks alot for all of the replies. Going to be tearing into it this weekend!

Is it a Lippert (LCI) system? Call their tech support number. They were very helpful. Had 2 jacks leaking down. He had me hand tighten the 4 valve bodies with a 5/16 Allen wrench. Plus I found an orange line (retract I think) loose enough to allow fluid to wetten the hose. After tightening the valves and the line, no more jacks leaking down. But it’s made me paranoid to the point of glancing down at the panel frequently and visually eyeballing the jacks at every stop.

[Mkayers]

Looks like power to the motor so I'll start checking there and see if that's dead.

Marty,

Manual says displays "low voltage."

Touchpad turns on, coach will not auto-level, "Jacks Down" displayed, jacks are retracted.
Low fluid level.
Check fluid level in reservoir. Fluid is low, with jacks retracted, add fluid to 1/2" from top of reservoir. If "Jacks Down" light remains on, call Lippert Customer Service.
Hope this helps

Yeah I unhooked the wires from the motor and jumped right to it from the battery & have no movement whatsoever. I think the motor is DOA

When I get that error. I reset the hack panel and it works again.

We need an update!!
Here is a video for a typical repair...

Ok here's the update! Lol. Had power at the motor but the motor didn't turn. Its not locked up. After some Google work I found another guy that replaced the brushes in his motor. Tore mine apart and they looked the same as his, one cracked in half, one jammed down in the holder, ugly. So as of now I have a set of brushes coming and will be here by next week. I'll report back then ��

[OldWEB]

Thanks and good for you!
While waiting, clean up all the "brush dust" that you can from the inside. It is carbon and highly conductive and at 12VDC not a big issue, but everything helps.

I had that issue with mine pump motor several years ago. But in addition the windings on my rotor looked darkened (overheated) so I decided to send the motor to a place in California that rebuilds them better than the COEM motors from overseas. Has worked without a hitch ever since and cost less than a replacement motor.

[Mkayers]

That place in California is where I bought the brushes from. I think it's $375 for a rebuild now.

[Mkayers]

Well motor is working great after installing new brushes. Now it appears it's not building pressure, just sounds like it's freewheeling. Still have a "jacks down" light even though they're up. Back to the googling lol.
