Two slides not working ALPINE 3700FL

[Natdancal]

Hi all new to this forum very nice to be here. I have a new Keystone Alpine 3700 FL we have been loving this RV. Five slides tow of them i just started having problems with one is currently stuck open and the other is closed. Who ever knows this model it is the front room living and the middle is the kitchen the back is the bedroom and bath. so the din-net and the kitchen are the ones that are not working. i tried the reset on the Lippert controller and it didn't work. so i'm thinking these two are hydraulic? i can here the in_command clicking when i push close. I went into were the hydraulic pump is and i noticed four fuses 5AMP and all four are blown.i replaced them and it happened again. I looked under both slides to see if there was something in the way of the slides and nothing looks like it. Has anyone had this issue? Thanks all ! i'm going to the newbie section and say HI to you all.

Are you connected to shore power or running a generator or just battery?

[Natdancal]

I’m currently on 110 cord just keeping the fridge and things running. I have had it hooked up like this for a few weeks and have run the slides in and out with no problems utilizing the other day.

I tried running on my generator but it’s doing the same thing no response from the in-command or by blue tooth on my phone.

What shape are your batteries in?
Even connected to SP fully charged batteries are required for slide operation. The converter doesn't have the oomph to do the heavy load items without batteries or risk damage the the converter.

The other three slides work fine. I think they are electric. The two I’m having problems are the two that are hydraulic.

I just checked the batteries they are fine

How did you check them? If you look at a panel reading while they are charging then you're looking at the voltage the converter is outputting. The true test is to remove the battery and have it load tested at an autoparts store or by using a hydrometer and checking each cell.

Nothing about the hydraulic pump will have a 5 amp fuse.. that motor will pull 50 amps or more most of the time.

There will be either a auto reset or manual reset breaker in the 6 gage cable running to the pump

The hydraulic landing gear all works

Your Alpine has the Equalizer System hydraulic pump unit most likely.. the four 5 amp fuses that blew are two the control relay panel for the equalizer system

Many Alpines have the Lippert hydraulic system but the newest models are starting to show up with Equalizer system

Here is the link to Equalizer Systems Tech Support as well as what limited information they provide on the hydraulic system in your Alpine

https://eqsystems.us/service-and-support/

Calling Keystone Customer Support for this system will be a useless venture..

Look thru some of their limited support information .. I suspect since all four 5 amp fuses are blowing when you try to operate the hydraulic slides that you have a wiring issues at the pump control, pump solenoid, etc…

*** you CAN also manually override and open or close the hydraulic slides on your Alpine .. locate the owners manual on the link I’ve provided and it will help you understand how to operate the hyd pump using a cordless drill.. yo7 would also have to manually open the Hydac valve located on the pump ,anifold for the sldies so that the pump can provide fluid pressure

This TS guide from Equalizer systems may get you pointed in the right direction

This schematic picture and a pic of fuse panel that you are blowing fuse at for further possible help… I’d be looking at a short from the harness to the control panel
