Technical question on my 1961
This is the switch inches away from the back roof-vent.
I assumed it to be a choice between AC or DC, with the middle being "off".. (Originally I assumed it was for the entire camper lighting, which was not the case)
But the (what appears to be factory) fan motor is AC only.
If you look into the box, you will see a bunk of wire(s) taped together up in the far corner. Could that be DC (I don't want to tear it all apart if there is no chance of it being DC)? I don't believe the little black switch within the vent opening to be factory. Indicating to me someone's messed with it. The motor vent holes line up PERFECTLY with the bracket holes, which is why I believe it to be factory.
It would take me 5 minutes to get the AC fan in and have it operational, but I would prefer to have a new DC fan (Which I already bought) up there.
Generally, the AC fan would work for us and how we normally use the trailer.
I understand I have two fairly simple options on how to get DC to the opening (from the closet or from the rear ceiling cabinet).
Is anyone familiar with what this switch did from the factory (As I said, I believe at least parts of the wiring in the opening have been messed with)?
It seems to me the transformer was to convert the AC to DC? But for what reason if the fan motor is AC only?
Any input, particularly from people who have seen this setup before would be TOTALLY appreciated!!!
