Fuse question

[jtintx]

Hoping someone will educate me:

On the 12 volt side there are a couple of fuses that I don't know what they are for. One is labeled PSJ and the other HHT. I'm guessing that PSJ stands for power stabilizer jack? Also, there is one labeled AC. Why would there be a 12 volt fuse for the AC? Or does AC stand for something other than air conditioner?

Thanks.

The A/C controls are 12V so is the stat and your control center at the unit. If that is what it stands for.

Try unplugging the fuses one at a time and see what you lose... Then I'd rebuild the list with what makes sense, or at least make notes on it (2 lights in bedroom and one in the kitchen, etc).. The HHT might be the hot water heater?

Thanks for the replys. Don't have water connected right now so can't turn on hot water heater and unplug fuses to test.

There happens to be a 24V inline fuse holder part number HHT. It could be supplying anything. Common items are power tongue jack, stabilizers, awnings, slides, etc.
