The fuse panel should be at the converter.

The Univolt converter is a rectangular blue box. Mine is located in the bathroom closet under a panel. I have four fuses in mine for four different circuits. Could be a blown fuse but in mine I also found that due to vibration the fuse holders can get loose and the fuse doesn't make a good connection. If it looks good when you pull it out or meters good then the fuse holder itself can be the issue.

I had troubles like that years ago and finally ripped the fuse box out and replaced it with a board that took the spade-type fuses: problems solved.

We have a 1976 soverign that the same things worked, thought the battery was dead, recharged it and found out that by testing that the number three circuit has a short in it, how do you find out where it would be

RichHog - I had the same loose issues.

Gosman - There are several connections
that can cause such a general outage. The
converter is on the floor, so get a droplight
and lay down(get confortable) and check them
all. A clipboard for notes and drawing is also usefull.
You can bypass a fuse with a simple jumper wire - for testing.
Oh yes...a single loose/corroded ground connection can
also cause such general outages.

Go slow and clean and tighten everything while you are doing this.
It is a PAIN and you do not want to do it twice :-)
every connection

For finding a short, get a shortfnder from JC Whitney.

I did some more checking with the fuse and found the fuse ( 50 ) had a bad inside wire, replaced that, now have power with battery charger hooker up. I think I have some other problems like bad battery and mice in the univolt charger. I am going to pull the cover off and see if they chewed some wires inside, what voltage should I have coming out of it? I checked the two small wires that have small fuses on them with the meeter that I have and also with a test light.
