Lost power to HWH Leveling Jack Control Board 200 series






Hi all, I recently took my 1995 Thor Residency to a shop and they accidentally disconnected the positive 12v lead to my HWH leveling jack Control board (200 series w manual joystick)

I need help in figuring out where to reconnect as I can't find the owner's manual or any detailed wiring schematics for my motorhome.

As you can see in the pictures above, the orphan red wire with a male spade is the positive lead wire to the control board. I determined this by testing with a multimeter for conductivity.

I suspect the wire may have been disconnected from the beige colored fuse block, but I'm hesitant to think that because I don't see any female fuse taps for the male spade to connect to. I only see two fuses with male fuse taps meant for incoming female spades.

Is this fuse block the likely place for the orphan positive wire? Is there another place I should be looking behind the dashboard? I've rumaged around a bit and couldn't locate any open female terminals for the orphan positive male spade behind the dashboard.

Is there a way to bypass and go direct to another part of the chain in the case I can't find the right place?

Thanks all.

1995 ford f53 (460) chassis.

    Hi Doug, I made sure ribbon connectors are secured. Think it might be a faulty control board?


    No, as much as I hate to say this. It is probably a GROUND(Negative) wire issue. HWH runs the grounds for the complete system to the Hydraulic Pump. You will see various WHITE wires connected to one of the 2 mount bolts that mount the pump to the steel mount frame. Make sure those white wires are all installed on that one bolt and that that Bolt is TIGHT. BTW, 11.9 volts is NOT good. You should have at minimum 12.6 to 12.9 volts. This indicates marginal battery, especially not fully charged. What service did you have done? Doug

    PS will leave post because it has good info for someone else

    I'm only getting 11.9 volts to the fuse block.

    I just installed a new battery about a month ago along with a new alternator. The alternator is charging at 14.4 volts with engine running.

    The battery reads 12.6 volts at the posts.

    Im losing voltage somewhere in the line.
