@Cthos: I see a bunch of neutral wires in the back? Anyway, for testing purposes, you can use ground instead of neutral. (neutral and ground are bonded at your panel, which is why this works. Note though, NEVER use ground in place of neutral in wiring -- it is a code violation, fire risk, and a shock hazard).

Cthos- Ah, okay, then what you're measuring is incorrect. You're measuring a difference coming through somewhere else that my brain is not in the right mode to figure out right now. What you should be measuring is the voltage between "to light" and neutral, or "to fan" and neutral -- though I don't think that will help in this situation anyway.

Where is the 83v and 12v measurements coming from (what two contacts)? Also, it looks like "power to fan" and "power to dimmer" marettes are redundant - there is just a small pigtail going to the incoming power line. Lose the pigtails, just use one marette - less to go wrong, and more space in the box.

comment Waterproof seal between two submersed pipes
Is the pipe pressurized (above 14psi, which is approx the pressure the outside of the pipe will have from being submerged 30ft), and if so, at what pressure? What is inside the pipe (I'm guessing wiring, but could be water, effluent,...)? How bad is it if the seal breaks, and water does get in (eg, do you want to really over-engineer this seal and have backups)?

Interesting, though long, article explaining vapor barriers: buildingscience.com/documents/digests/…

comment Do I need a moisture barrier between my bedroom and attic?
@Karl: my opinion: that's too hard to get right, and the wax paper is just not as good as 6-mil plastic. If you don't get it right, and you end up with mold in your insulation or walls (possibly years later), the repair cost easily trumps the small extra amount of money and time to just do it right in the first place (install 6mil plastic).

It would be useful to see all the wires, labelled with where they're going. I'm tempted right now to say that probably the dimmer is sensitive to electrical noise generated by the fan motor or switch, but without seeing the full wiring diagram I can't rule out a cross connection between something.
