Today when I woke up power in trailer was working with no issues. Started the generator and it ran for 30 min and when I shut it off, I no longer have power to any lights, ref, water pump or monitor. Start the generator and everything works. Check GFI and fuses but all look ok. Where do I look next?

Try the fuse by batteries it happen to and my friend on our wws the fuse holder and wire are to small

yes my fs3000 did the same, it melted the fuse and holder, I replaced it with a 40 amp circuit breaker instead of a fuse.

Isn't the fuse between the batteries and the generator? If so, how would he be able to start the generator?

there is a seperate feed to the genny starter, the same thing happened to me, no power untill I started the genny, the fuse goes to the 12v power on everything else but the genny starter.

So the fuse is up near the batteries? I don't recall ever seeing a fuse up their. I will go to storage and check it out. Thanks for the tip!!

usually kind of hidden up there, most use a 30 or 40 amp auto reset fuse under there, usually like $5 at the rv place. The new AM-PM off S22 in Ocotillo has them in their RV dept.

Good to know!

The fuse at the batteries was the issue. Fuse blown and melted the holder. Looking to change out to a resetable breaker.

I knew it have you ever seen those huge fuse holders and the fuse is about an inch square thats the one to get the wire is about 10 or 12 guage its a plastic fuse
