Univolt Voltage

The ac voltage at Univolt is 116 volts. It is showing 10.2 dc voltage. Is there a problem with Univolt? This is on a 1970 Overlander.
Thanks, Joe

univolt

Could be the univolt or it could be poor / corroded connections between the source and the univolt.
What is the voltage where the A/S is pluged in ?
If you have a voltage drop between the source and the univolt then you have a resitive connection ie 120 VAC at the source and 116 VAC at the input to univolt the problem is most likely before the univolt if no drop in ACV the univolt should work ok at 116 VAC and the problem would be in the univolt.

Don't rule out a faulty braker or your test meter.

The voltage output from the older univolts will not read correct, "unless" a battery or a dummy load, is attached to it.

The correct voltage output for the old univolts "WITH" a battery connect to it should read between 13.0 and 14.0 volts DC.

If it reads less than that, then the univolt is gone.

Andy: Where do you take that measurement? at the battery? at a 12v outlet inside the trailer? or at the univolt itself?

At the battery since that's where you need the charging to occur.

andy is correct as usual, you can see the actual results of battery vs. no battery in this thread. has some good tips on repair as well!
