How exactly do I go about bench testing this fan?
Because I have a 63 Overlander the 12 volt
dc and 110 ac were originally totally separate systems.
There is a City - Off - Battery switch. I'm guessing here - but when you hooked up at a campground and have it switched to city, the power would come in and be stepped down by a separate transformer to run the fan. When the switch was on battery it would be powered by a different 12 volt
At some point the PO disconnected the 12 volt
transformer (that's whats in the picture upper left ( I think?) I'm guessing it doesn't work.
I have no clue how to bench test this! The two black wires are 12volt? Can I use a battery charger? Exactly how do I do this?
Do transformers like this (that step down 110 ac to 12 volt dc) still exist?
I would love to keep this original fan with the ability to work with both systems. The replacement fan from VTS is only 12 volt.
