recently bought a 1142 electronic ignition for my TO35 Ferguson with pertronix 40511 coil. Tractor is 12 volt, negative ground.I have 12 volts at the coil. (power lead comes down from switch to - side of coil(as had)where the black wire from distributor connects and red wire connect to + side of coil) engine cranks just fine. continuity thru the dist. cap is good. still no spark.No current coming out of coil to dist cap.it is like the electronic module is doing nothing. Had some difficulty seating the magnet spool onto the rotor, but is seated all the way down. the dist cap cover closes just fine. there seems to be a natural .025 gap.Why no spark. what else can I test. No meter jump on coil while cranking the engine. Is something backwards? 12 volt coil is wrong? same wiring as had b4 electronic ignition add on. Had no spark condition prior to the upgrade. thought the coil was bad.had no ballast resister b4. Don't know if old coil was 6 or 12V
