Circuit Tester for Determining Function of RV Vent Hood Wiring

Question:

I have a 96 mobile home with a vent line exhaust fan above my stove top, I replaced the fan but ignorantly didnt take a picture/ can’t remember how the wiring went. There’s a light bulb in there too. I’ve been tinkering with it and can’t figure it out. The way I had it wired up at first it ran, with the switch off. When I turned the knob that will allow me to run fan with lights or without I’m just tripping the breaker. I don’t know man, if you could help or point me in a good direction it would be great. Thankyou

Since it is unlikely that even the maker of your 1996 mobile home will know the wiring color scheme for installing a replacement kitchen vent hood, your best bet is going to be testing the wiring with a probe tester like # PTW2992. This will help you confirm which wire in the RV is ground and which is 12V hot.

The Fan-Tastic Vent Roof Vent # FV801250 that you referenced uses WHITE wire for GROUND and a BLACK wire for +12V.
