I'm chasing a credit dot on my DM. So far no luck. This state is at the beginning of a ball with the ball still in the shooter lane. You flip the left flipper that in turn energizes the right ramp diverter. In 75% of the cases it triggers the right ramp exit, which scores 250k and also lights Quick Freeze. If it happens on the next flip/diverter energizing it will give you a freeze.
Switches involved works just fine, I've changed diodes on the ramp exit and shooter lane (same row). Last time I had an issue like this on TZ I had to brute force it by changing every diode in the row and column of the affected switch. Is there a smarter way to find the culprit?
