Leveling Jack's Damon Challenger

[J-R-S]

Need some help with leveling jacks for Damon Challenger Motorhome: When got to campground I put the Leveling Jacks down - but they went DOWN TOO FAR AND TRIPPED THE SYSTEM. Have tried several different ways to determine where the RESET is. Have been working on it for weeks, talked to factory rep. and followed their suggestions but nothing helped. ANYONE HAVE ANY IDEAS??????

Hi Jack! What brand and model leveling jacks do you have?

[J-R-S]

The brand is Power Gear, don't know the model number, can try ti get if it will help.
Sure hope you have some ideas I haven't tried yet, very frustrated.
Thank you.

usually the 'trip' is the BUSS BREAKER in your battery compartment, mounted on the wal maybe, and usually a 100amp size - the little 'flag' might be protruding, which is a sign that it has tripped - simply push it back in and you'll have power to the legs.

While it can be confusing the those new to leveling systems, typically the CONTROL PANEL is operated by 12v power from the CHASSIS, but the hydraulics for the legs are powered by the HOUSE Batteries, which is why one can 'work', while the other does not, etc.

[J-R-S]

Some of what you wrote doesn't seem to apply to my jacks.
This is what I've done over the last few weeks:
Checked all fuses
Manual says:
Inline Fuse under dash, but
nothing there.
Nothing in battery
compartment.
Can't find reset.
12 Volt to pump.
Way past frustrated!
The Jack's are Power Gear brand.

Thanks for your help.

If the jacks hyper extend when grounding, it could be a bad pressure switch. During the auto phase of operation the jacks ground one at a time to prevent wracking of the coach. There is a pressure switch on the control valve block that senses line pressure. When the pressure reaches 300 psi, the control module stops the pump and selects the next jack. If the pressure switch has failed the jacks will continue to extend until the jack's motor stalls tripping the circuit breaker.

It's the circuit breaker that I can't find.
The "Control Panel" on the dash is dead.

This is what I've done over the last few weeks:
* Checked all fuses
** Manual says:
**** Inline Fuse under dash, but
****** nothing there.
*** Nothing in battery
****** compartment.
*** Can't find reset.
*** 12 Volt to pump.

The Jack's are Power Gear brand.

If you happen to have any other ideas please call, my number is 231-225-1381 name is Jim.

Thanks for your help!

The jack control panel is powered by the chassis battery under the hood. Just behind or beside the chassis battery will be a 100 amp DC circuit breaker. This is the battery power for all Thor MC equipment in the front cab (exceptions are the radio and power ports). Below the drivers left foot (at least on the plant 750 coaches) will he the coach's supplementary fuse and relay board. You have a plant 850 coach so it can be different as each plant has its own engineering staff. Anyway the fuse for the jack control panel (but not the jack motor) is in that circuit board as is the two relays powered by the circuit board. The reason it is wired this way is so the emergency retraction system will work even though the store/use (master power) is in store/off.

Thank you so much, I will check it out tomorrow, if I manage to find and fix the problem, that will be great!

Jim, what year is your Damon? Without the model number of the leveling system, it'll be hard to really help, as Power Gear, now Lippert, has several different models. When my system(LCI) overextended, it popped the main breaker in the front of the rig, mine was next to, and below the hydraulic pump.

[J-R-S]

Thank you so much for your continued efforts to help me.

Motorhome is a 2005, 36 ft.
Went out to look again for any numbers.

Only thing I can make out on the pump (in front of the radiator), is

1-gal Lorz
PN 500910

Wish I could find more.

My cell number is:
231-225-1381
Thanks, Jim Sherman

That is exactly where my pump is. The DC circuit breaker for the leveling system is to the left, and below that, on my system.
This includes your pump assy; https://lci-support-doc.s3.amazonaws..._82_l0521_.pdf

[J-R-S]

Again, many thanks for your efforts.
Reviewed everything you sent me, but I have a little different setup, see attached pics.

My DC breaker is located someplace else.

Thanks again! Jim

[HarryS]

That large red cable coming from the front of the pump assy is the 12VDC input to operate it. Follow it and you will come to the circuit breaker.

[J-R-S]

Tripled checked the red cable and unfortunately it goes straight from the battery to the pump.

Thanks again Harry,
Jim

That's very strange. That means there is no circuit protection for the pump or the battery. If you have a meter, could you check for power at the pump, where the red wire attaches?

[J-R-S]

Have power but my control panel is dead

[J-R-S]

Only have had few mouths found wires pulled out of auto level repaired it was little black one with 4 wires

[HarryS]

What does that mean, only have had few mouths? So, back to square one, need to find the fuse that powers the panel. Do any lights come on, on the panel? Flashing, or nothing at all.

Look on page 7. The schematic shows 2 power wires, one, from the power gear solenoid, which the battery power cable attaches to, goes from there to pin 8 of the controller connector, check for 12VDC there. Also, there is a 6 pin connector as well, which inputs things like parking brake, and 12VDC from ignition. With the key on, check for 12VDC there as well. If you don't have it there, follow the wire until it terminates at a fuse panel or an inline fuse.
