Everyone was very helpful with my question about upper helm access, now I have the next problem.

With the switch on the main power panel on, when I go to the aft head and turn on the blower switch, the breaker in the main panel turns off. I get it, there is a short somewhere and I'm hoping it's the blower motor. The only problem is, with no blower motor noise, I don't know where it is.

The front head blower is in the bilge/engine room, so I look in there. Don't see anything obvious with the exception of a blower tube coming from the port side, going across to midline and hanging down from the floor (top of engine compt)

Is this the right tube or should I look elsewhere. Just where is that blower supposed to be?

Thanks for your help.
