Confused! Wiring in a Shur-Flo vent fan to a '66 Carvelle
Hello, hope someone can help, I've searched the forum and still can't quite figure this out. We burned one board already by wiring incorrectly, don't want to burn out the new one. SO, we have a '66 Caravelle that had a ceiling vent fan. We removed that and installed a new Shur-Flo vent fan, but the wiring is confusing us.
The airstream has white wires and black wires. The fan has Red & Black wires. We think the black wires are power, the white wires are common, but there's a black thin wire just hanging there not connected. Is this the ground? And if so, do we connect it to the common white wires (seems to be wired that way in other parts of the airstream) or do we find a ground by connecting that black wire to the skin somehow?
Help would be much appreciated...
Thanks so much
