Jay Flight 29RKS Battery Disconnect

Last week we picked up our 2016 29RKS from the dealer. During the walk-through, the dealer rep mentioned removing the fuse to keep the battery from draining if we were going to be storing it for more than a couple of weeks. I assumed there was a simple in-line fuse in the positive feed from the battery, but when I took the battery out today for winter storage I saw no such fuse. Can anyone tell me where it is located?

When I got my new TT I removed the battery and put in the garage charging in a trickle mod for the winter.

Yes, the battery is out for the winter. I'm wondering about the fuse for in between trips in the summer, so I don't have to actually disconnect from the battery terminal.

Here is a thread on them. I installed one on my rig a few years ago. There are many different types depending on the application.

I'm not familiar with your TT but the fuses I've seen are in a black protective rubber enclosure very near the battery, either inside or just outside the battery case and are inline with the +. If you have a single wire connecting to the battery there may be multiple wires spliced into that, one lead goes to the emerg brake switch and another headed for the coach and distribution pannel. I think it will be after the emerg brake wire on the lead headed for the pannel.
They look like this:

Congrats on the new Jayco!

One other related question did you tag the black TT battery cable POSITIVE, or put red tape around the end and the white TT battery cable as NEGATIVE. It is amazing how many people can accidentally reverse them when they put the battery back in. Will cause a bunch of other problems.

Just checking


The MAIN 30 amp fuse should be 10AWG (usually) wire, mine was GREEN (with a black fuse case), that was connected directly to the POSITIVE battery terminal. Does JAYCO use automatic circuit breakers on some of the new trailers. There may be 2 other wires connected directly to the battery also, if your TT has electric brakes it will have a "Break-away" switch wired directly to the battery. Sometimes the dealer will wire the Tongue jack, fused 12VDC lead directly to the battery also.
