ras, check voltage on pins on hall effect switch under rotor in dist. battery voltage on far right pin as it is mounted,less than .5 vdc on middle pin with interuptor in aperture near battery voltage when not in aperture. Far right pin should be ground. let me know if it worked for you.937-322-0657 Brian
