No power to slides or jacks

[barbil]

My '03 Holiday Admiral has no 12V power to the jacks or to either slide. I can hear a relay click when I press the out switch for the bedroom slide. Interior lights work and normal chassis and house voltage shows on inside panel. Anyone have any hints as to where I should look? Thanks.

Sounds like chassis battery is dead..jacks are off the chassis battery...start engine or try batt boost and start engine and let her run. you won't be able to move slides with engine running..but you should be able to retract the jacks. Or let it charge up before trying it again.

If that doesn't work, check in your battery compartment for a popped relay. On mine there are two - on yours? no idea. follow the cable from the battery that goes to the hydraulics and it should be on that cable somewhere.

Make sure battery grounds to frame of chassis are clean and tight. Both house and starter batteries.

Are these slides and jacks electric or hydraulic? Of course, if hydraulic, they will have a 12 volt electric motor driving the pump, but it could be that your motor is running but the hydraulics are messed up. So, if you have hydraulic units, you need to find that pump and check for fluid in the resevoir and if low, leaks. It's probably in your basement, or in the front cap by the generator.

Thank you all for the comments. Seems to me that, since the unit hasn't been on the road for a year, (lot rot), the problems could be poor grounds. Have to "chigger-proof" myself and just start digging and probing. Thanks again.
