SkyKingII 1 Posted February 22 Share Posted February 22 Am looking for some sage advise as to how to proceed to find cause and fix what is causing my leveling jacks not to desend and level. I have 2004 Doplomat 40'PDQ,with RVA 3 point jack system Manual leveling hydraulic system. With ignition in position to operate jacks the switch panel to operate jacks lights up properly but when I push to operate I do not get the familiar sound of the pump working and nothing happens. I have checked the fuses in FRB with volt meter and all seem to be good. It seems like I am missing a fuse somewhere...is there possibly an "in-line" fuse that I haven't found? I get no sounds from @solinoids/hydraulic resevoir when switches are activated,however when I press switch and observe battery guage in hall I can see drop in voltage when switch is activated,telling me switch is working?? Any and all suggestions will be welcome,this is first time of any problems with these jacks other than ocassionally adding fluid to the reservoir! Thank you in advanse for your input!

Dwight Lindsey 13 Posted February 22 Share Posted February 22 Bruce: Have a look at this document: https://help.brazelsrv.com/hc/en-us/articles/360045550852-RVA-Leveling-System-Turns-On-None-Of-The-Jacks-Deploy-Pump-Does-Not-Run A quick read would have me look at the "interlock relay", which is intended to prevent operation when the ignition key is on.

sjamiejones 1 Posted February 22 Share Posted February 22 Bruce, I had a similar problem that I traced to an in line fuse next to the pump/solenoid in the rear of my coach. I looked at the fuse repeatedly and it looked good but in the end it turned out to actually be open. Wasted a lot of time for no good reason. Link to post Share on other sites
sailingmyway 1 Posted February 24 Share Posted February 24 I'm with Bruce there is an in line fuse on my 99 Windsor. I saw a d took note of it when I was looking for something else.FYI Hwh jacks have the same thing. Link to post Share on other sites
