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?

Bump for catching Phoenix.

Thanks for the inputs and the additional reading. I'll see if I can make such "box" on my switch matrix. There's definitely closed switches at play here.

Oh, the credit dot reports the diverter is stuck closed as the ramp exit switch is not supposed to get hits when it's open.

For Internet karma and a perfect playing DM. I replaced the resistor and diode on the optoboard hosting switch #67 and the ghost hits vanished.
