Found it!

I also discovered that the illuminated buttons have one setting for indoor use, and one for the sled. I thought I broke it after switching to the sled wiring and the lights went off. Need to use the empeg more often.

I forgot to shut the empeg off for two days , so on wednesday the interior lights didn't even turn on. I had to call for a tow car to get me going. It was one of those days. I was really stressed out - going to a meeting - and then this thing with the battery happened.

Had to wait thirty minutes for the tow car, and broke all records (and laws) on my way to work - coming in 15 minutes late for the meeting. Exept, the meeting was an hour later... bugger! Took me two hours to get my heart rate down...
