The other thing I saw wiring up a Zeus tonight was that the SS wire can go into those screw on terminals in a couple different ways. One is the proper (good) fit and the other is a very poor (too low?) fit which can come lose or just isn't very tight period. I noticed when I first put a wire on wrong, it lit up but has a erratic pattern and behavior, probably because it was the data wire and wasn't getting a good signal. So I removed it and put it back in and that time it was a much better fit ... and on my retest, the light acted much better and no poor behavior anymore. Just a thought.
