First Toad wiring, then HWH 12v compressor, now HWH keypad no lights. INOP

One thing after another....

First thing that happened was when hooked up to the toad wiring and the parking or headlights were turned on, the coach resettable fuse would trip. The lights would go out and then when the fuse reset they would come back on.

Then I found the 12v HWH compressor was/is not turning when needed.

Then both bay lights on the drivers side won't turn on.

Now I just returned from getting fuel and the HWH computer is not working. No lights, no nuttin.
I can't get the coach level and I am concerned I won't be able to get it to ride height in a few days.

I believe there may be a short but where.

Any ideas my biggest concern right now is the HWH computer.
Thanks

For the HWH computer, open the hatch over the instrument panel and make sure that the multi-wire plug is securely plugged into the back of the HWH panel.  Mine vibrates loose every so often.

Whew!  Thank you so much!
It looks like the plastic clips that held it in place are broken. Now I don't have to worry about my fridge being level, and whatever else keeps me up at night.

Back to watching youtube videos about multimeters and finding out why my bay lights etc, are not working. I though they were all related.

Thanks again

Ed,

Pull the white breaker cover in the basement (on one of your basement walls) You will find the breakers that supply power to various things hidden in there.  These breakers are manual resetting. That is there is a little button on them that will have to be pushed back in to get the breaker to reset. One of those breakers supply power to the basement light circuit. It is likely that if all the lights are out you have tripped the breaker. Use the eraser end of a pencil to reach in there and push the reset button.  Try this first before you start tearing into all the door switches. If it is just a few lights it may be the door switches as they are quite thrifty made.

The breaker for the bay lights may be behind something like a wad of wiring. Mine was. I used a Popsicle stick to reset it. Use something non conductive. The breaker switches are very small, so have your good glasses on. Hope this helps.                            Like Pamela and Mike said it could be the door switches. I removed mine and did without. Don't like them anyway.

Thanks guys!

I know about the breakers behind the fiberglass. I've been resetting them with fingers, pencils, swiss army knives, you name it. (LOL) with no luck.

We are staying with family (one of the last Duck farmers on Long Island NY.) with full hook ups. Thirty acres on the Peconic River. When people think of NY they think of NYC. Not here in Calverton L.I. Uncle doesn't raise ducks anymore, he leases the land to a fellow who grows evergreens for his landscaping business. Wild turkeys and deer are our neighbors. Last exit on the Long Island Expressway. Paradise.

Ed,
Do you have power to those breakers?

Without actually putting a meter on them, I'm going to say yes. There is only one breaker labeled "Stor Lts.", and the fluorescent fixture on the passenger side works.

Edit
Would you know where the drivers side would be grounded?

Ed,
On our coach the basement lights are grounded at the light fixture.  I would think yours would be the same as a system ground for the basement lights would be a lot of extra cost with not much benefit.

Pic 662 and  608  both have electrical and air connections?  The pressure switch will have an air diaphram  and at least two wires . The two wires may run to the main power relay ( usually supplying  ground ). The main relay should have 4 wires  or more . IMHO
 Googleate the part numbers that are in the pics.
