don't get too nervous, most of went on in this tread about unpluging is just tounge in cheek.

the way the capacitors are wired to the transformer creates a ferroresonate circuit.

simply put, it is somewhat self limiting as regards to charging current.

primative, yes! when compared to what is available today.

plugged in for a couple of days or longer will most likely be o.k.

just remember to check the water level in your battery cells regularly. i check mine once a month (i have a magnatec in my excella) you may want to check more often until you get a feeling for how much water you WILL need to add.

most people unplug the older univolts so they can have a normal conversation or sleep at night.

My converter is a Litton Triad-Utrad ....so it says
It hums for 10 sec then pops the house circuit breaker
The white wire mentioned on the end plate isn't connected to anything
The unit is sealed by rivets so I'm assuming it's not meant to be serviced by a novice .....that means me
It doesn't have internal fuses shown in pics of a Univolt
I'm enclosing a top veiw and the end w/ specs
Is it scrap?????I could use some help

310,

what white wire are you referring to?

there should be two, one to ground the 12v circuit, the other is the neutral on the 120v side.

i see in the pic the white wire on yours sez power on, that could be for an indicator light.

John,
The 120 & 12 volt wires are no problem.
The white wire is apprx 18 ga. I think you are correct that it would be for a indicator light
How about the tripping the breaker problem? I feel the unit has seen it's last days. Would it be wise to have it repaired?

i think by the time you pay someone to look at it you would be better to get a new one.

there is a 30 amp unit for sale on ebay, here you could use that for a basis on what a replacement might cost.

however, there is still hope. the 74 excella that the unit in this post was installed has the univolt powered on the GFI circuit. it shares about 4 to 5 other outlets. when we went to power it up we found the GFI tripped from the exterior outlet being damp.

have you tried the univolt on a seperate circuit?

if it is junk toss it, but you might kick yerself if a new inverter snapped the breaker too!

can't hurt to try it plugged into a different source, just be careful!

Thanks John....I removed it from the trailer and tried several outlets and...... POP.....I'll s...can it
I checked out ebay and there is a Iota unit.......know anything about these??

The Argost part on ebay looks like a fuse box only.....
There is no transformer in it
My fuse box is mounted on the wall and has the same configuration of fuses
