2016 Greyhawk Electrical

[Dangerboy]

Hello Future Helpers,
I installed my house battery with reverse polarity on our 2016 Greyhawk 29MV, but never applied power to the RV with the latch relay/main power switch. When my wife reported no power on the landing gear control - I looked and saw the error.

With the battery in correctly the landing gear operated as advertised and power came on as it should with the main power switch. I thought, "whew... dodged a bullet on that one".

Not so fast. I noticed no power to the thermostat, the inverter, and the on-demand hot water system. Well, off to Florida we went as snow was in the forecast and we wanted out of upstate NY ASAP.

On the second night I had a little time to troubleshoot and found the three reverse polarity fuses blown in the electrical center. Replaced them, but no joy on the three items above.

Further troubleshooting yesterday reveals - all circuit breakers are good (measuring 120VAC on each) all fuses are good (measuring 12VDC on both sides). The inverter has 12VDC on the inputs. The Thermostat fuse under the cover is good but I read nothing on it.

I'm lost on what to check next. Any ideas folks? A neighbor here in the park said to pull my inverter from under the bed and check it over for a fuse or a popped breaker - I'll do that today.

What I'm really stumped on is that thermostat. It reads nothing. How is it powered? It's a device that controls a DC powered unit and the AC powered AC. So it's kind of unique.

Thanks in advance for any advice. Is there something I left out info wise?

I'm on shore power and I have run the generator but still do not have the three things mentioned above.

In my 2016 Greyhawk there's a 50 amp circuit breaker in the compartment where the battery is.

Theres a spade fuse in the wiring harness of the coleman thermostat behind the wall. Not sure if it will help you or not. The power inverter has a small breaker on it for reverse polarity. The tankless hotwater has a breaker as well, although I think its thermally activated.

I believe there is a reset button on the side of the inverter, my inverter is under the bed. Lift the foot of the bed and remove the plywood cover to access the inverter.

I just happened to take a picture inside our battery compartment, for that gentlemen who forgot to label his wires before taking out the battery.


This is a '16 31FK, but I'll bet its the same for the 29MV. Perhaps someone could circle the breaker/fuse for him here?
