have a gottlieb surfer and just diving in. flip the machine on and this stepper unit with 5 cams in the head just locks the coil on it. i can't identify this stepper as the label is missing. anybody have some guidance as to what unit this is? seems if i manually hit the release coil on the AX (reset control relay) the stepper coil releases. also noticing that during this the SCM is spinning non-stop, and the score reels are not attempting to reset.
