trouble shooting help (Lippert stabilizers)

[railroaderone]

I have the lipert stabling jacks under my camper and the front set will no longer work with when switch or remote.

Dose anyone have a wiring schmatic or troubleshooting guide for these.

Thanks in advance

I doubt you will find a schematic, but just start at the logical position the switch and check for power and work your way around from there may be something simple like a fuse.

[Herk7769]

Yep,

Here you go.

That is one strange electrical interconnect.

[trozfast]

Did you have a low battery lately? Some models need to be reset if it had low voltage to it.

I am not sure which Lippert system you have or if there is even more than one, but my sister and her husband have a 5th wheel with a Lippert leveling system that has been nothing but trouble (they do not have a Forest River coach) since day one. My brother-in-law suggested you contact Lippert directly about your issues. While at their RV rally last month, my sister and her husband learned from the Lippert rep that if you contact them and make arrangements, that Lippert is 1) repairing or 2) replacing faulty leveling systems with their current leveling system, which is apparently not as problematic as some of the systems installed in late model TTs and 5th wheels.

Again, not sure what is going on with your system but know my sister and her husband have had trouble with their Lippert system since the day they purchased their 5th wheel new in 2014 and Lippert is going to make things right at no cost to them. My brother-in-law suggests you contact Lippert now as their situation has not gotten any better. Good luck.

It's the up/down switch not an interconnect.

On my 2015 261bhxl the fuse panel for the remote operated items was behind the main panel under the fridge. It was mounted to the wheel well. I unplugged shore power and removed the four screws holding the panel. Replaced fuse. Hasn't blown since a year later.

That is an interconnect drawing and even though one of the pdf dwg's shows it that way it is not correct. That auto reset breaker is supposed to be in series with the OEM protection device (fuse or whatever it is) so if there is an issue the auto reset breaker will open before the OEM device is affected. That way the auto reset device will reset automatically if and when the issue (over current/short/ low voltage/overheat etc.) is resolved. The way the drawing is shown the auto reset breaker will only open if the jack motor has an issue in one direction. If when switching the input to drive the jack motor in the opposite direction and there is an issue the OEM protection device will be affected. I think the pdf dwg was misinterpreted when it said "6. The supplied 6A reset breaker must be wired in line to rear stabilizer jack". I don't have a unit like the one referenced and I don't know if the installation of this circuit was actually done this way.

[Herk7769]

The first breaker near the battery protects the wiring, switch, motor, and battery from shorts; the auto-reset breaker between the switch and the motor protects the motor from stalls when the stabilizer hits full up or stalls from trying to lift too much.

The thermal breaker auto-resets when it cools down (and hopefully the motor will cool down at the same time).

Corrosion at the limiter terminals can cause "opens" that prevent operation.
They should be located and inspected.

Also check the frame ground for the stabilizers as the screw may have rust where it penetrates the frame.

I'm sure that is the intended function for the auto reset breaker but the way it is shown installed it will only do that when the motor is driving in one direction only. The auto reset breaker is not switched to the opposite side of the motor input when the motor +12 volts and -12 volts (ground) is switched. If the auto reset breaker is installed before the switch it will open no matter what direction the motor is turning and an issue arises. That's all I have and I'm done. Thank you.

The auto-reset function will work in both directions and it's function can easily be checked by anyone who has one of these stabilizers.

A DC motor will rotate in both directions, clockwise and counter-clockwise, depending on whether +12 volts is applied to one terminal or the other (with the ground wire connected to the remaining terminal). Again, easily checked with any 12 volt DC motor and a DC source.

A fuse will work in a DC circuit whether or not it is on the positive side or the negative side of the load, as the current is the same on both sides of the load.

This is not a "right or wrong" opinion situation. It is basic DC circuitry and easily verified with some simple experiments.

When I bought my unit the rear stabilizers did not function. The dealer had to replace the circuit board for the system. Once the wireless remote gets added into the system it gets a bit complicated. It is under the fridge in my trailer.

Our unit has Lippert front & back Stabilizers.They Both are supplied by power from the same source protected by 1 20A fuse! The fuse is located in the Main fuse panel below the Refer! When we deploy the Stabilizers,and Both pads have Touchdown we continue 2 seconds before Release,on Retract we judge by Sound for finale Release! Youroo!!

Couldn't resist. This is your example you posted. Notice the auto reset is connected to the switch common terminal (green wire).

[Herk7769]

While true where that limiter is installed, it really does not matter. It was just a convenient place to install it from the factory.

Do your electric stabilizers twist when they are fully retracted back up to the frame? Our rear one twists a small amount, but the front one twists quite a bit. The dealer stated that this movement is normal. Is it?

There is some play in the mechanicals and they will move about some as they fully retract; but examine the mounting bolts and make sure they are tight.

Done some trouble shooting and I have 13.7 volts getting to the switch and a positive 13.7 leaving when trying to lower negtive 13.7 when trying to raise but the motor will not energize, these readings were taken at the motor leads.

Am I assuming right that the motor has gone south

[Herk7769]

Yes, most likely.

FYI , if you flip the switch you will need to reverse the probes at the motor as well. There really is positive 12 volts being applied to the motor; just in the opposite direction on the winding. This switching is done mechanically by the selector switch.

This reverses the poles on the rotor causing the shaft to rotate in the opposite direction/
