Atwood water heater problem

OK... me again.:) I had a few minutes when I got home so I checked the wires on the hot water tank. I put a test light on them, with the remote switch on, and I had power to the brown wire, but no power to the red. And it seems like no power to the circuit board. I looked at the remote switch too, and there is power there.
I know this because when I pulled it away from it's mount, the white wires slipped of the connection and touched another wire, blowing a fuse. oops. :) Anyway, I'm not sure which wire is which on the switch. White is obviously live, but what are the rest? I looked at the wiring diagram in my manual, but it mentions a green wire from the switch, and there is no green wire on the switch. I have attached a pic(I hope). Maybe someone can explain what each wire is?

EDIT... Tried to attach pic, but won't let me :( I guess I should read Forum rules before I try to attach a pic.!

I'll describe the wires then..... There is a dark blue, next to a doubled white, then below these are a red and a black wire. Clear as mud?

EDIT... I made the pic of the switch my Rig pic so you should be able to see it....maybe.
