Step No Operation Specifi 1 Check all connections in primary and secondary circuit 2 Remove secondary coil lead If spark occ from distributor cap Hold 1 4 inch from engine while cranking and observe if spark occurs 3 Check Voltage V 1 while 1 Volt max cranking 4 Check Voltage V 2 ignition Normal batt switch On points open 5 Check Voltage V 2 ignition 41h 6 Volt switch On points closed If over 6 If under 0 6 Check Voltage V 3 ignition 0 2 Volts ma switch On points closed 7 Check Voltage V 4 ignition 0 7 Volts ma switch On points closed eation Possible Trouble urs check Distributor cap Rotor Spark plug wiring Open in ignition circuit used during cranking Ignition switch not closing ignition circuit used during cranking Ground in circuit from coil terminal to ignition switch Ground in coil ery voltage Low battery Points not open Ground in circuit from coil to distributor Ground in distributor Ground in coil Ground in ignition circuit used during cranking or in the lead connecting the coil to the resistance wire check Contacts not closed Loose connection in distributor Distributor not grounded to engine Faulty contacts if faulty recheck Step 5 Loose connection between coil and distributor Resistance wire out of circuit due to shorted or incorrect wiring Starting contacts of ignition switch stay closed Harness has too little resistance Resistance should be 1 8 ohms Coil primary is open check Loose connection from resistance wire attachment to coil through ignition switch circuit to battery Harness is open or has too much resistance Resistance should be 1 8 ohms x Contacts not closed Loose connection in distributor Distributor not grounded to engine Faulty contacts if faulty recheck Step 5 NOTE The voltage drop across the dis tributor points should not exceed 0 125 Volts K Loose connection from resistance wire attachment to coil through ignition switch circuit to battery
