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
