Washout,
The short is in the wiring to the rearmost wall lamp in the "Jumbo Slide". As you will know from your days with the 35FLR, this lamp is wired from the front lamp through the wall. Being unable to pull a new wire, using the original wire, likely due to some tight turns in the wiring, the fix was to disconnect the rear lamp for now. I'll add this item to my list for the next visit to SC. As I'm not anxious to open the wall or ceiling on the slide the final fix may be to run a new wire on the bottom of the slide.
Hopefully you will forget all about this if we happen to meet up again this winter - which I hope happens!
Jim
