Have a 6 million dollar man that I am repairing. The original mpu had leaky batteries so put a weebly mpu in there. Also put a new rectifier board and repinned and replugged most connectors.
So the only issue I have is the pop up post between the flippers does not work in gameplay. It however tests fine in test menus.
Verified that switch in top hole which activates pop up works in test menu along with rollovers in mid playfield work.
When I ground each of the coil signal wires or drive transistors from solenoid driver board, they all work including the pop up and pop down post.
In gameplay, when the ball lands in the top hole, it makes the appropriate sound and the light for the pop up post comes on, however it doesn't pop up. And when I hit the lower rollover switches, the light goes out.
It's almost like there is a software setting to disable the coil, but the menu doesn't detail anything like that.
Any ideas or further tests?
