Ok, I got my new solenoid driver board in and the EBD was up and running. One small issue..the game decides to reset at random durring game play and will give the game tilt alarm for no reason as well. (Some times one, some times the other)

One of the first thing we did (with the help of Logical Highs) was to check the +5 voltage. It came out to be around 4.93 to 4.96 There does not seem to be any rhyme or reason to when the game resets.

The power board is an ultimate MPU board, so it is not the original power board.

Anyone have any ideas here?

Please bear with me if this is something blatantly obvious, I'm still a noob at pinball repair.
 
You probably have corroded and or broken molex pins inside the connectors. I would check the 2 connectors on the right side of the mpu board, these are normally the culprit since they are directly above where the battery on the board has leaked at one time or another. Also check the small molex pins on the right side of the solonoid driver board as well.
 
nah, I've got more stubborn games then this...Just needs a little more tlc is all
