DC fans reversed
I just realized today that the 12vDC fan for the stove hood and the bathroom vent are running backwards. These are the small cheap DC motors. However, the blower for the heater is running correctly....

I kind of agree with this but there is an even easier answer.
I'm cross trained. Certified Electronics technician, (Also an Engineering student) with Electrical training and experience though never certified or licensed in that field.
As an Electronics tech I'm used to black being Ground or Negative when working on automotive stuff.. Like that 12 volt fan.
But in HOUSE wiring black is HOT,, White is neutral (And in RV use will usually (NOT ALWAYS) be ground.
The idiot who built the think hooked the black wire to the black wire and the other wire to the other wire.. That simple.. NORMALLY that is how I would wire things too.. but if I'm working on 12 volt in a motor home.. I METER First.
