It‘s a really tight space but I think I got it. I‘m measuring -0,13 volt. (I measured from pin 4 to 8, that‘s what you meant, right?)
By the way, IC802 is directly connected to Focus Drive and Focus return, so it could be responsible for my first problem, but how is it related to the one I caused? I mean, IC804 is responsible for Loading Motor Assembly and Carriage Motor Assembly. How likely is it that my shortcut grilled that one?
