Joker Poker
Gottlieb, 1978Joker Poker SS reboots during gameplay. During gameplay when pressing either flipper or pop bumper a few times JP reboots. new ps installed, new mpu to driver cable (no diodes in cable) installed. Was working for a few weeks with new ps and cable. Seems like something in the 25volt circuit common to all coils? I am not leaving this JP till I get it working!
Thanks in advance for any help, Walt
The circuit board ground mods were already done when i purchased machine. I just replaced both bottom panel rectifiers. The pin still reboots when you hit the flipper or pop bumpers
Usually a reset is from the power supply, are the connectors good, especially the one from the CPU that provides the +5?
Anything on the same circuit, like a fridge?

Agree with shacklersrevenge on the connectors. I believe the are a know problem. Might want to buy a new PS to CPU cable. I purchased one and I think it was $13 shipped.
