Hi Steve,
Well, if the MPU is detecting the TILT switch then it will behave
exactly as you describe.
So try this - put the game into switch test. Note that SW 07 is shown in
the display. Now unplug the two plugs on the right hand side of the MPU
and see if the 07 goes away. If it does then there is a closed Tilt
switch (or pinched wiring) somewhere in the game. I'd be checking the
SLAM Tilt switches - the one on the coin door near the hinge or the
lock, and the other is usually on the underside of the playfield
somewhere near the flipper area. I think that is most likely your problem...
