Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.
Please give me a few minutes to type up my answer here. Thanks! And sorry for the delay as our site was down for a bit.
Good morning! Thank you for bringing your question to us here at Just Answer. I have an RV repair facility and work on these for a living and I fully understand the frustration you can have when things aren't working the way they should.
I am sorry to hear that you are having problems with your slide out and levelling system. And I apologize for the delay in someone getting to your question! Thank you for your patience. Sometimes we get overwhelmed with questions and some of our techs may be on vacation. I just got back from one myself.
The two most common causes of this problem as you describe it are batteries that are failing to deliver their rated amperage OR a dirty ground lead in the system or at the battery ground to the chassis. These would be the first two things we would check in the shop.
There should be two batteries installed for best results on any slide out. Get your meter and check it to be sure that the charging device is putting out the 13.7 to 14.2 VDC that these put out when working properly. That would be to the fuse block and the batteries.
If not, and the fuses are good I suspect that this is going to be a tripped shortstop breaker up by the batteries or perhaps a DC breaker by the main load center. That is the most common reason for this happening. Check that and get back to me. Short stop breakers have to be within 18" of the batteries by code and have a red cover over them. Silver post and copper post and a small black button on the copper post end. And it would be very helpful here to know whose load system this is here.
Then check the DC voltage out of the load center and see what that is. In the shop the first thing we always do is to load test the batteries to be sure they are viable. Surface voltage really doesn't mean much if they are beginning to fail. Most places that sell batteries can do this for you. Just be sure that you mark the cables first and take a photo so you are sure to get them hooked back up again correctly. Easy to get this wrong if you don't. About 80% of all the electrical questions we see here are a result of batteries and cables needing attention.
I hope this points you in the right direction here. Please get back to me again later if you need additional assistance with this as all follow ups are included in our one time fee. No time limit. Thanks! Randall in RV
