I recently aquired a used ST4 and have been having trouble getting the thing to work. Last night (since it was warm here) I was bound and determined to get it to work since I had all night if I needed to. I read the manual again and was going to use Wil Milan's article as my step by step guide. Got everything hooked up and plugged in the camera to start the cool down process. According to Milan's guide the head is cooled down when the X and Y values flash zeros. After a few minutes, only zeroes flashed. After 10 mimutes, random numbers were starting to appear in those X & Y values although not all the time. The entire time the guider head was capped and in a black bag so I don't think (or know how) light could have reached the head. There is where I stopped for the night. Is this normal for the X&Y values to display those random numbers?
