2017 forest river nitro 31kw

[Jphillips79]

Since I got back from the last camping trip I have discovered I have no 12v power if I am not plugged into shore power. Batteries are charged and jack still works. When I got ready to load up last trip I undone the shore power and the last thing I did was run in the slides. Acted like battery was very weak so I just assumed batteries were discharged. I work in the automotive industry so I can chase wires. I’ve started by checking the breakers on the tongue of the trailer and so forth. No luck yet.

Main point of this post is to ask if anyone knows where I could get wiring diagrams for my toy hauler?

Thanks.

Everything I've ever come across when looking through posts, are you'd have better chances of riding into the mountains on a unicorn and catching bigfoot. As I have seen most people do with basic knowledge, and you with your background having an upper hand, is start systematically checking 12v power at the batteries and then working your way back to the panel, etc. Most jacks are wired straight to the batteries. Earlier in the season I had a breaker go out and unlike my previous TT our new TH had them mounted underneath on the backside of the front tongue cross beam. Mine had the same symptoms as yours, shore power everything worked. 12v only, nothing.

How did you determine that the batteries were fully charged? Did you use a multimeter to test, with the trailer unplugged from shore power or did you go by the control panel idiot lights?

Also it's virtually impossible to get schematics or diagrams from any of the Towable divisions.

Unfortunately, since wiring diagrams are not available for trailers, you should check for blown fuses. That may require you to trace down the wiring. Perhaps someone in the toyhauler forum could help.
