Imagine 2800BH blowing Fuse 5

[beutler64]

I have a 2018 Imagine 2800BH that has blown fuse 5 "Slide-out Lights" twice. It does not blow as soon as replaced so it is not a dead short. I've used an inductive amp meter to check load on all the circuits I can identify being supplied by it... slide-out lights (one above couch and one above table), USB port in bedroom, 2 pass-through lights, and front LED accent lights with switch in pass-through. Everything test fine, total load with all 6 circuits on is only 3 amps. I tested while moving the slide in and out incase it was an intermittent short in the harness and tested ok. I'm sure there is a circuit I must be missing. I contacted Grand Design support for suggestions or schematics and they were no help at all.

Has anyone else ran into this problem or have any ideas of other things to test?

Thank you!

Possibly a loose
Connection or skinned wire that is
arcing against metal with movement in the
Coach.
I had an issue like this with fuses blowing on a blinker due to a marked light wire shorting out when the coach rocked or swayed
Probably a long shot and hard to find. Just an idea though.

Does it always do it when the lights are on for some amount of time? is it intermittent? And is there always a delay of some minutes (or hours or whatever) once the lights are on?

If it is after a delay and it does it every time then it might be a bad connection (loose, not crimped well, etc.).

I'd start at the fuse panel and make sure that it is only those lights that are on the circuit. Check for loose connections there.

Then I'd try to drop every light and make sure all connections are good (maybe new crimps or at least reconnect wires if they are in those quick connect snap connectors).

Make sure the fuse holder is in good condition too.
