OP

Quoted from bigguybbr:

Today I received my Alltek ultimate solenoid board and installed it in my Stern Meteor. I start up the machine and start a game. Everything is working and playing fine then all of a sudden the displays start flashing, the game locks up and eventually resets. I power cycle the game and do a memory clear on the mpu board. I restart the game and go into the self test and run it through the tests a few times and again it locks up with the displays flickering. I tried reseating all the connectors and ran the tests again with the same results. Finally I put my old solenoid board back in, and now the runs without issue.
My question is whether the new solenoid board is bad, or is there something else I could be missing? Any insight is appreciated.
