So I'm stumped on this one,
Picked up a roadshow and reds mouth would not stay up.
Thought a stripped gear was the problem but on closer investigation I found that the motor is stuck always on in the down direction.
It does change direction when its supposed too but when it should be off its moving down,
Ted is fine,
I've compared all the components on teds side (in circuit) to reds and they seem ok.

With the driver board connected (game in attract)I get +12v at pins 10,11
+12v at both 4 (red on) and 8 (red direction)
0v at both 2(ted on ) and 6 (ted direction)
But with the board disconnected I have only 12v at 10,11
To me this points to the Dual H-Dive motor board and not back at the power driver board.
Could the IC (ba10339) be the problem?
Any ideas or advice welcome!
Thanks
