Sorry if my reply is specific enough. Check the opening/closing of the switches on the A relay, the ABCD Relay, the Bonus Unit Stepper and Bonus Unit relay.

If you have a jumper cable, try jumping the switches one at a time on the rollovers that don't work to eliminate the possibility that the switches are bad (or need cleaning). For the scoring problem, I'd look at the 100 point score reel. I believe there are a set of contacts on the reel when the reel is on 9 that enables the next reel (1000's).

Quoted from Nikrox2:My Hokus Pokus started just adding scores all of a sudden. Even when you touch a flipper button. Either side. Totally out of the blue. Quick ideas or just cleaning switches ?
Check the switches on the playfield, particularly those behind a rubber, for the contacts being too close. Often when the rubbers age and they lose their tension, the slightest vibrations (like flipper movement) can cause the condition you describe.
