Blown 25 amp fuse

[Jaycoht18]

My 2018 Eagle HT 28.5 RSTS has blown the far right (set of 3) 25 amp fuse twice. Two different campsites, plugged into shore line. Battery runs dead so I am not aware of the trigger until all starts to dim and fail. Any thoughts?

Those fuses are for protection when the battery get hooked up in reverse polarity.
You had better check your connections.

Thank you for your response. Just checked and it is correct.

Is this a new rig or did everything work fine last season?

They pop when you plug in to shore power.
Assuming you replace them while still plugged in, does everything work correctly while afterwards, battery charges, etc etc

New last season. Yes worked fine for remainder of stay. Plugged into new site and worked for 36 hours. Replaced fuse and was working until I packed up. Traveling with pets and concerned that it could happen again. Was pretty warm when I returned and found all shut down and battery drained.

I would start looking for a loose connection. Check, clean, and tighten all of them. also look for chafed or chewed on wires.

Appreciate the feed back. Needle in a haystack.

You do know black is positive and white negative on campers … right?

[Jaycoht18]

My battery cables are red and black. I have red to the positive and black to the negative.

Any update Jaycoht?
I’m interested to know what your problem ends up being.

Nothing yet. Had a repair service out and they checked everything. Replaced fuses and ran unit for a while. Nothing. I will be back to unit in a few days and see if it occurs and hopefully know what the trigger is.
