This is a 1970 unit with the original Univolt.
Didn't someone say the voltage output is adjustable? I examined the Univolt and didn't see an obvious adjusment.
I disconnected my battery (for obvious reasons) and continued to use my 12 volt
lights as needed. Isn't this a no-no?
I am plugged into shore power, 120v.
The old style Univolts were subject to failure, when a good power surge took place,
That was coorected many years ago.
Every auto charging system has failures, but when they are very low, that's good.
Airstream's current Univolt, has been in use for a number of years, with a very low failure rate.
Most of the failures you read about, are for the Univolt 5 systems and older.
