So I dumped holding tank and put chemicals in toilet and hit flush....the macetator pump wouldn't stop. Couldn't even figure out where to find a fuse or breaker.

Flipped toilet breaker, unhooked all wiring coming into toilet, still ran. Finally quit on its own (Smelled hot). Only turning off house battery would stop. Toilet flushes now, but have no idea if that pump is working or not.

So I'm wondering a couple things: 1. Where can the breaker be for this be? 2. How do I determine if it's working?

The Tecma runs on 12 volts DC so you're looking for a fuse, not a breaker. I think my fuse is 35 amps.

12v toilet hence fuse.

Much more convenient if you cannot get shore power or run the generator.

Most of my house fuses are in a forward basement compartment below the navigator chair.

Most frequent problems in our MH are electrical problems.

Tecma toilet in my 2007 Allure has a high amp breaker in the battery bay above the inverter.
EDIT: added picture
EDIT2: Same thing happened to me, seems like toilet brains took a "sh*t" and turning off breaker and back on brought back some sense to the brains.... lol

Brian, I flipped off that toilet breaker when this happened, and it keeps going. Couldn't find a fuse labeled "toilet", do I'm stumped.

It shut off after it smelled hot and worked ok for a few hours and is now doing same thing.

I did find a 4th set of wires behind the TECMA, they were under the piping. Disconnecting those shut the pump off. When hooked back up it work fine for a several flushes, then did it again. Trying to reach a TECMA tech....been on hold for 1 hour and 21 minutes and have moved from "position 25" to "position 5". Pff....

ps Brian, I don't think I ever actually turned the breaker (that you show) off. I pushed the red button and the lever dropped, but didn't act like it tripped anthing and the toilet still had power...

The issue was the macerator would not shut off. As indicated I found a set of electric plugs behind (there are 5 sets) that killed power. After it set a while it worked - but had the same issue on a couple of other occasions.

I finally reached Thetford via email and they gave me a testing routine, which I completed, and they diagnosed a bad "controller". I found one on Amazon ($285) and installed myself. Actually fairly easy - you have to unbolt from the floor an pull out so you can reach everything in back. Took less than 1/2 hour. Seems to work fine.
