I thought I had this solved but apparently no. When a ball enters the left ball lock hole, the game stops. The next ball doesn't eject and the only way to start the next
ball is to tilt. After tilt, the ball will eject from the saucer. I'm a bit stumped as to why this is happening.
Troubleshooting already done:
Replaced MPU board (NVRAM Weebly) - Awesome board btw.
Replaced driver board - known good working board
Repinned all solenoid communication connectors MPU - J4 - Driver board - J4
Placed game into switch test - All switches activate properly, including ball lock switches when ball rolls over each one
All 1n4004 diodes on ball lock, as well as upper and middle switches tested
.05uf 100v capacitors changed on ball trough microswitches (diodes checked as well)
Ball trough diode checked as well
Still. Same issues happens. Game plays fine all through aside from when the ball locks in upper left saucer. Once this happens, game stops. ball does not eject into
lane and you'll have to tilt the game to get the game to continue. If I pick up the ball from the ball lock saucer and manually place it into the trough, the last trough
switch doesn't see it and I can't continue the game unless I tilt the game. Anyone have any ideas?
