Slides and Level Up not working, Hot red wire tripping 50amp auto breaker

2016 Montana 3950BR.
Hoping you guys can help, had issue this weekend where Level Up and Slides would not work (no power to Level Up Panel), could hear 50 amp breaker clicking/resetting. Replaced breaker and still slides and Level up would not work. Did find while replacing breaker that there was a red wire coming from the breaker that was warm/hot. I disconnected that wire, breaker quit tripping and everything started working as normal. Problem is (or maybe not a problem...lol), I don't know what that red wire goes to (it goes underneath belly), but I checked everything I could think of and seems to be working. Any ideas?

If it is a 10 gauge red wire, it may go to your tank heaters?

.
Would lights for tank heaters still come on in control panel if it was for the tank heaters?

Yes, the lights come on when the switch is on.
The switch controls a relay

One time when we had a similar problem that I spent an entire day chasing, it turned out to be that we coiled up the pigtail and stuffed it in the pin box and as luck would have it, the red / hot wire inside of the pigtail plug landed straight down on a screw causing a dead short! Those screws no longer protrude into the pin box.

Lippert issued a directive to up the breaker to 80 amps.

The original breaker that provides power to the hydraulic pump motor also usually has an additional wire attached that feeds the 12 volt side of the inside panel and this is where power from the converter comes through that charges the batteries. This circuit goes through the battery disconnect switch. When you replace the 50 amp breaker with an 80 amp breaker, connect the battery cable to the battery terminal of the new breaker and the two cables that are connected to the load terminal to the same terminal on the new breaker. You will need to make the holes in the ring terminals a bit larger to fit the larger terminal posts on the 80 amp breaker.

Ours came from the factory with an 80 amp breaker. Lucky me, I didn't have to change it. When it's cold the Lippert levelers really are working hard to do their job! And remember lower voltage causes higher amperage, that is why Lippert suggests running levelers and slides while on shore power. That way the converter can help out.
