Need help with a nuisance "Clock Broken" error.
When game is powered on, clock cycles fwd/rev normally. In clock test mode, the fwd command (fast and slow) does nothing (no movement). In reverse, fast and slow work fine and all optos register. The clock opto board was replaced at one point by prior owner and has pinwizard printed on it.
I reseated the associated connectors at the motor control board and it fixed it for 1 power cycle, then came back. Do I have a bad motor board (A-16120)?
Quoted from LTG:Or flaky connector.
LTG : )
I did look closely at the motor board and noticed a small amount of leakage around the capacitor. So replacement board likely needed (or repair). I'll check the plugs too while it's out.
Very weird side story, but in the span of one week, 3 of my 6 games went down for one reason or another. With the IJ, it was the motor control board for the upper playfield. What are the odds!
I'll report back once I get this sorted.
Thanks!

Just to close the loop on this one, a replacement motor driver board seems to have fixed it. Thanks!
