I just purchased a BSD from the York Show last week, & have fixed several issues w/ the machine. As of last night the ball launch failed. I did however go into test mode & checked the switch associated w/ the launch. The launch switch tested just fine, but the coil test in regards to the launch never activated. The coil itself appears to be good, & moves just fine back & forth fluently when moved by hand. I have already reseated the four connections J205 - J212 w/ no such luck. Does anyone have any insight to this issue?
