THOR #8765
Exclamation Mystery module

Pulling my rig out from winter storage, I find my monitor board dark, and my house battery dead. Suspected the solar panel was not working last fall. In my search I found this module next to my water pump and have no idea what it's for. Obvious add-on, as the power is connected to white and black/green stripe near my tail lights. Has a "buzzer" 2-pin connector, and two "sensor" 2-pin connectors. Don't have a clue where to look to trace wires.

2000 Thor / Majestic, Ford F450 V-10, 27'

Thanks, Duane (Road Rookie)

I believe that is a flux capacitor. It came out in 1985, but only as a prototype.

I spent some time trying to figure that out with zero results for you.

I can say that the one clear chip is a hex inverting buffer, and at the bottom there is a PIC microcontroller so whatever it does someone had to write some firmware for it.

Were those plugs disconnected when you found it? (If they were I would suspect that someone removed its functionality from the rig without removing the module.)

No this was connected when I bought the unit but never seemed to do anything, connected or not. Not knowing what it is makes tracing wires next to impossible.

Can you get a better view of the area around the water pump, and see which loose wires are looking for something to be connected to them?
Good luck!

I don't see it in your pictures but is there an FCC ID number on it anywhere?

Not finding it anywhere - I tried to get a clear pic of all writing on it. Google search was useless.

Can this be your battery charging controller for either solar panel or 110v trickle charger?

I have been hoping this this the controller for my solar panel, but the hookups are confusing. A two-pin connector for "buzzer", and two two-pin connectors for "sensor". Power is low voltage. Definitely after market.

I don't have any loose wires per say. Voltage (power) wires tested good for low voltage. "Sensor" connectors disappear into the deck under the water pump and I'm having difficulty trying to trace where they go. Next step will be to put a tracer on the wires on the solar panel up top and see if I can get anything back there. Still have to figure out why my house battery went dead over the winter even though I started the rig up every 3-4 weeks. Will be hooking up to shore power this weekend now that I can get outside.

How long did you run it for when you started it?

Varied - anywhere from 20-30 minutes to and hour. Sometimes I would tinker around while running it.

Just guessing here, but "sensor" could be for temperature sensor for batteries. "Buzzer" could be for a "low voltage alert". I have been looking at solar charging units and some of the ones I have been researching have these "features"

Thank you for your diligence. I would hope this helps me to narrow things down. The disturbing part is, based on visible evidence and days of searching, I have no recourse to find who made this and why. Usually numbers and names on circuit boards give clues - not the case here.
