Working on my firepower - blowing the fuse for the special solenoids - testing shows that all outputs from the driver board are going to ground.

Pulled the input plug, no change.

I would appreciate idea's for troubleshooting - thanks!

Do they go to ground with the game on and off, or just when on

Just when on - after the game boots up -

Also - Pulled IC9 from it's socket... no difference...

Remove J13 from the driver board (Special Solenoid Inputs) and see if they still lock on.

Remove J12 (Special Solenoid Drives), boot the machine up. Wait 5 seconds. Then reconnect J12 to see if they lock on.

Have you replaced the 40 pin interboard connector?
