So which coil error #s do you get with either of the Bally coils, error 1 or 2?
The Gottlieb knocker coil for HH should be A-5195, 12.3 ohms, #26 gauge wire with 1300 turns. If 10 ohm still doesn't work then maybe the drive transistor is indeed the issue as the old coil may have locked on for whatever reason and fried itself to a total short?
