Univolt alternative

I
I have a 66 Overlander that has been sitting quite awhile. Would like to prepare it for possible sale. Is there an alternative to a univolt or a way of testing it before I buy a new battery? Handyman husband has passed and I don't think I will be using it again. Prefer now a B-van.

The fastest and safest fix is to replace the Univolt with a new style converter. Check out Bestconverter.com or call them. They are very knowledgeable in replacing these original Airstream converters. Ed

With the battery out, you can have someone power up the trailer with shore power and measure the voltage at the battery terminals. If it is between about 12.5 and 13.5 volts, the converter is probably good enough to install a new battery.

Since your intent is to sell the trailer, you only want power so that you can show what is working and what is not to avoid the buyer's concern that nothing works and discounting the price to replace everything. Some of the older trailers relied on the battery to smooth out the power from the converters.

This will fix it. The old Univolt is probably not working well if at all at this stage.

Sorry about your husbands passing.

Another option is just to replace the battery. Tell the buyer that it should have a new converter installed.

You can test the system with a regular car battery if all you want to do is to get the system operational. You do need a battery with the univolt system because it puts out a lot of AC ripple. The battery can be charged with a regular car battery charger if the univolt is dead.
