CHECK

POSITIVE WIRE TO COIL FOR VOLTAGE--KEY "ON"

POSITIVE WIRE TO COIL FORE VOLTAGE--KEY "START"

IF NONE, WITH "ON"

CHECK RESISTANCE WIRE/ BALLAST RESISTOR.....THIS WOULD COME FROM THE "ON" POSITION OF THE IGN SWITCH TO THE COIL

THE INITIAL "FIRING" MAY BE FROM "I" TERMINAL AT THE SOLENOID--THIS IS NORMAL AND CORRECT (IF YOUR IS SET UP THAT WAY---REFER TO THE PICS AND EXPLANATIONS IN THE "BOTTOM", OF THE LINK I SEND YOU)

MAKE SURE YOU HAVE CORRECT COIL

COULD BE A FAULTY IGNITION SWITCH

DO YOU HAVE POINTS?....OF ELECTRONIC IGNITION?

SORTA USE MY LINK, EXPLANATIONS AND PICS TO TEST VOLTAGES, WHEN AND WHERE THEY SHOULD OCCUR
