Major electric problems with 2016 Vegas 25.2 MH

[Welshdancer]

Hi all,
I am brand new to this forum and have no idea if I am doing this right.
Anyway, I have lost power to my windshield wipers, my mirrors, my back up and side view cameras, my heater/ac controls and my nightshade.
I have checked all the under dash fuses. All were okay. Any ideas?

Well that sucks! I can’t really offer anything concrete except that you’ll just have to grab wiring diagram and a multimeter and do basic troubleshooting. See where the affected circuits share a common connection, track down the specific fuses involved and finally just start chasing voltage until you find the break(s). If all of the problems happened at the same time there’s probably a common point of failure which should make it easier. Good luck.

Put your vin into the thor website for all diagrams..did you call thor customer service? A common fuse must no be working..can you swap new fuses in each at time to troubleshoot? It can be hard to see a fuse break

All those items are usually powered by the chassis battery. Look under the hood near the chassis battery for a 100 amp DC circuit breaker. I will bet it is tripped with the yellow or red flag showing.

I don't know any other suggestions, but good luck and welcome to the forum

THANK YOU, THANK YOU, THANK YOU!!!!!!!!!!!!!! That was it.

Now, what do you suppose caused it to trip?

[Hugh.vines@att.net]

Could have accidentally hit it when someone was under hood CW service manager accidentally hit mine

Glad you found the issue and were able to get things up and running again.

Water in the wires somewhere was my problem. My story - New coach; second trip - It had rained the night before and there were a few drops of water on the jack panel. Nothing in the front cap worked including the step. No power to the fuse/relay panel down by the drivers left foot. Traced the power cable through the wiring maize behind the instrument panel to the fire wall connector, then to the circuit breaker hidden by the battery under the hood. That CB is now annotated on my pages of wiring diagrams for the coach. Before I tried to reset the CB, I grabbed a heat gun from the shop and used it to evaporate the water from the driver's left side panel. I reset the CB and everything was now working including the strep. We were only about one hour late in starting our annual March migration to Florida.
