Bought this old Mati Hari from this guy that had in a warehouse for god knows how long for $250 . It looked in pretty good shape with decent play field and back glass. Of course it didn't work but figured I could get it running . Had voltage issues so rebuilt power board. Next mpu was too far damaged (acid like so many of this age ) so bought new mpu board. Worked for about 1 hr then locked a coil on chime box . Didn't notice until I smelled something, shit ! Shut It down and cut off coil. Left pin on as I was working on repairing display then heard another coil buss. It was on the kick out ball launch. Caught this one right away with no damage to coil.
Checked all transistors on driver board and even replaced the transistor on that particular coil just in case . Still stuck on . Checked switch on kick out and it is not stuck . What is going on ? Any suggestions would be greatly appreciated .
