Looked in and around breaker box with no luck. Did find another inline fuse behind the fridge. It’s good. Not aware of location of converter.

I'm pretty sure the second picture in your post above is the front of the converter. I suspect the fuses are behind the front panel that must come off somehow. It does not look like an Elixir converter to me, but I think there will be two 30A fuses in there that are for protection if the battery is installed improperly. I've found they also blow if you have a high demand on the battery with the trailer plugged into shore power.

Figure out how to take the panel off and see what's behind it. It's safe to do so as long as you are NOT plugged into shore power.

No fuses behind access panel of breaker box. No obvious converter there either. Just standard breakers.

Dang! I really thought that was where the converter was. I'm totally out of ideas now. Maybe someone with a 2001 HiLo will see this and give you better advice. I STILL think there is a fuse in the battery charging circuit that has blown.

The converter will have to be in the lower half, and it SHOULD be close to where the shore power comes into the trailer. I'd think it would be on the street side of the trailer.

Thanks for your input, Jack. I’ll update this thread when I find a solution
