I have a 12v fan I want to run on shore power

Novice question for my 1975 Trillium 1300.

I am installing a Maxxfan, the instructions say attach to 12v power source. Can I just splice it into the wires above my light fixture above the sink? The light runs off shore power, 110v, so will it still work on the fan or am I about to blow something up here?

No, you can't. 110v of shore power will burn out 12v motor in the fan.

you don't have any 12 volt lighting in your trillium?

Not sure, I'll bust out the ohmmeter, most lights only work when I'm plugged in

"most" or "all"? That makes a big difference.

Dietrich I think you need to more familiarize yourself with your trailer and its components.

Do you have a 12 volt battery? Is it taking and holding a charge? Check your fuse panel make sure all the fuses are good. Check the light bulbs... typically they are the bayonet style like cars have... unless a prior owner installed led fixtures. You really want to know what is and works on 12 volt. do you have a water tank and pump...does it work? Tapping into the 120 ac line will be a costly mistake.

Most trailers have 12V DC lighting, run off the battery. Household AC current can come in via the power cord to a converter, which recharges the battery. The battery can also (usually) recharge somewhat from the wiring going to the tow vehicle.

If you had 120V AC lights, they would have the household screw-in base just like in your home. This would be unusual.

I wonder if you already have a converter, but no battery?
That could explain why your existing lights only work when you are plugged in.
