I have a Secret Service that randomly resets during gamepkay. I read that it might be a bad diode so I've changed a number (not all) but problem seems to be happening more frequently. Used to happen only during a really long ball but now much more frequent. No bad switches or coils on startup diagnostics.

I'm not the best at troubleshooting but have been successful changing transistors and replacing coils. Could use some help on how to locate/check components.

Thankful for any help. Hosting Christmas and trying to get games working...
Secret Service

wayout44,

Thank you for your help. I hope it is this easy - I checked all the connectors especially CN1/CN2 and was trying to get it to reset - 5 games later - no more issues.

Hopefully it was that simple.

Thank you.
