Install Electric Landing Jack

[irishrover]

Need help! I am a new owner of a Jayflight 184BS and spent the afternoon installing a Lippert Electric Landing Jack. However, when I connected the wiring to first, the positive terminal on the battery - it didn't work. I then tried wiring it to the external wiring box on the front of the trailer. It didn't work. I had previously replaced the inline 30amp blade fuse with an inline 30amp breaker. Could the problem be the inline breaker connections or where do you recommend running the wiring to? A picture from someone who has a 184BS showing the wiring would be helpful.

Directly to the battery with an in-line fuse/breaker is how it should be connected. Sounds like you either have a bad jack or it has an internal fuse that is possibly blown.

Thank you Grumpy. I thought it was right but now will try checking the breaker then look to see if there is an internal fuse which I don’t think there is? Hopefully the Jack isn’t defective as bought it over the winter and just installing it. Returning it will be a heavy problem! Thanks again!

I don't mean to belittle you, but you are running power through a switch, correct?

Be sure you have a good ground to the tongue. The paint may be insulating that.

X2, I lime to use a couple star washers one one of the bolts to bite into the metal.

Which lippert stab jacks did you get psx1 or psx2 . I have attached a pic of the switch wiring for a psx2 (has 2 motors so you see 2 sets of three wires). Mine are wired to the battery thru a 30 amp reset breaker located on the a-frame of trailer.

Red is power, black is ground and yellow and blue feed the motor(s) to extend/retract.

Will double check that. Raised bracket on lippert Jack but mounting screws have raised edges that remove paint as you tighten. Bottom of bracket not touching bare metal but screws should do the trick. Will check! Thank you

Not stab jacks. Tongue check which should be a simple install. Reminds me of IKEA “ easy assembly” Not! Lol.

So with the electric tongue Jack removed and the manual back on I tested the breaker and current to the electric Jack and all good there. I then touched one edge of the electric jack mounting flange to one screw of the manual mounting flange to see if it grounded to the frame and the jack worked. So we have a grounding issue when the electric jack is mounted.
I then made sure bare metal was showing all around the screw holes on the electric jack and mounted it on the tongue - it didn’t work. Somehow it isn’t grounding when mounted. Does anyone have a miracle solution? I have tried everything the DYI videos show and even ran a ground from the battery to a screw on the mounting flange. It is a bit frustrating to say the least.
Thank you

Ref the Lippert tongue jack. Got it fixed. Grounding was the issue and the in line breaker wasn’t resetting completely. Fixed both and bingo we have a working jack. Thank you to all of you who took the time to respond. Appreciated.
