No power to leveling system

[Sweeney]

Hey all,

New to the forum and also new to RVs

I recently got a new to me 99 adventurer 35c

I brought it home yesterday to prep for the season, and I cant get the leveling system to power on. In park, parking brake down, and tried both engine on/off and all key positions. I've checked all the basics of fuses and switches that I could find, the parking brake lights up on the dash when engaged so I'm assuming the switch is working, verified the plugs are seated on the board yet still nothing when I try to turn it on, no lights or noises etc. All batteries are brand new and fully charged. its a HWH leveling system, I'm not totally sure what one yet but based off my searched today I believe its a 200 series, I will confirm when I get home today. I've read somewhere that the slide and leveling system share a main relay, if that's the case the relay should be fine as the slide does work.

I plan to look more into it when I get home today from work, but was hoping to get some direction from someone who knows a little more about motorhomes then me haha.
