electric landing gear upgrade

when using the landing gear on my rig, it always seemed sluggish, as well as making the circuit breaker cycle at times.


i looked at how it was wired and it was pretty standard (cheap, but standard lol)


the power went to the up/down switch which was a double pole double throw center off rocker (heavy duty) and then to the motor.


i disconnected the wires close to the motor and wired the motor side into an albright solenoid outputs, and the switch side i wired to the wires that used to go to the switch to the control wires in the solenoid.



the red post i connected to my batt + (using a circuit breaker)
the black post i connected to chassis ground.
for these 2 wires i happened to have some automotive 2 gauge battery wires laying around and i used them, but anything 8 gauge or bigger should be plenty big enough.


this is the link to solenoid i used:
https://www.amazon.com/Unversal-Sole...dDbGljaz10cnVl





my landing gear no longer is sluggish, and i no longer cycle the circuit breaker.

I know on my hydraulic ones, it started doing the same thing, with the circuit breaker interrupting and then resetting. From this site, I read that it was my factory 50 amp that was the problem, which needed to be replaced with an 80 amp, which Lippert recommends. Crazy if they know this is an issue and they are not coming with the 80 amp as standard equipment. Glad yours is working again Grumbolt

The 2007 electric jacks did not use a 50 amp breaker. They have an inline 30 amp blade fuse.

Montana finally heard us and are now installing 80 amp circuit breakers for the pump circuitry in the new rigs. It only took 10 years or so.

mine had a 30 amp circuit breaker on it when i got it (second hand) i can only assume the previous owner made that change.



in my case, the same circuit breaker still powers the landing gear, but with the larger , shorter wiring it seems the landing gear gets higher voltage, therefore lower amperage is needed and it actually works better.


it does make sense that the circuit breaker looked like an afterthought in its installation!


thanks, grum.

Ours is so slow that I've considered going to a two motor type as we had on our last and SOB 5er. I'm not sure that rewiring the Lippert LG would make any difference to. it but it/s worth a few hours of my time even though it's the upgrade on my now pretty short list.


Grum - do you have a wiring sketch or was it just seat of the pants and electrics knowledge?

sorry for the late reply,

i had a death in the family and havent been on much..



i didnt have a schematic but can tell you exactly how to do it and as a bonus you get to keep your existing switch!


on the relay i posted,
the red dot is battery positive (through a fuse or circuit breaker)
the black dot is ground
the other 2 go to the motor.


when you disconnect the existing wires from the motor, one of them will go to green wire, the other will go to the black wire (both pictured here at top)


if the landing gear goes in the wrong direction, simply reverse the motor leads.




for what it is worth, i was considering a dual motor setup also until i did this upgrade.

Where is this relay located? What year is your rig?

Sorry to hear about the family situation.


Thanks for the update. Might be a good thing for me to look at and hope it might help our poky landing gear.
