Would like to know where to find the ATS on my 2003 Ultra Supreme 8328?
I'm not having a problem, but would like to know where it is should I have to. Also, what does it look like?

I'm not sure where your ATS would be located, but mine is really close to (just over) the generator & the shore power cable, which in the Sun Voyager 8351 (gas) is in the bottom of the rear closet/dresser drawers. It is impossible to see without mirrors. I'm not sure how I will access it for repair or replacement - obviously, the unit was installed before the cabinet or coach rear cap was installed.

The unit is similar size to the converter, with lots of heavy wires attached. It is just a "typical" electrical box, maybe 8"x8"x4" high. I have pictures, though unfortunately not here at work. Mine is labeled (with a cheap label) "Lyght Power Systems", though I think GS uses other manufacturers as well.

Mine is under the master bed.

Mine is a Iota model ITS-50R and located under the cedar chest insert at the foot of the bed.
Replaced it last June due to the printed circuit board blowing a hole in it.
Here is link to see pictures of what what a 30 & 50 amp models look like if you have a Iota. Not sure what other makes look like, but I imagine they are similar.

Thanks guys. As soon as it warms up here a bit, (8 degrees right now) I'll go out and look for it.

Finally got out to look for it, and found it. It's right on top of the convertor under the bed. Very convenient. I had the plywood cover off under the bed several times, and never noticed it. Duh! Maybe because the label was on upside down and never really read it.
