Finding wiring problem - help?

[Myka]

Mike, yes I know, KISS!!!! The fans are a known issue with these fixtures. I assume the seller was telling the truth, and I have no reason to question that. It's neither here nor there, besides possibly tracking down why the fans aren't working. Today didn't work out quite as planned, so I didn't get a chance to work on the fixture, but hopefully Thursday or Friday.

If all else fails, I will just re-install the fans and run a wire out to an outlet and they can be on 24/7 for all I care. I little extra air movement around the tank should doesn't hurt anything.

Hopefully, something has disconnected during shipping.

I can set the fixture to demo mode which goes through all the dimming and the fan dimming too, and they don't turn on during the demo either.
