IGNITION TEST
To trace a fault in the low-tension circuit, switch on the ignition, and turn engine until the distributor contact points are open. With a voltmeter (0 to 20), check the circuit as follows.

CABLE-BATTERY TO STARTER SWITCH Connect the voltmeter between the supply terminal of the starter switch and a ground point. No reading indicates a faulty cable or loose connection.

CABLE (BROWN)-STARTER SWITCH TO TWO-WAY FUSE UNIT A.1 TERMINAL Connect the voltmeter between the fuse unit A.1 terminal and ground. No reading indicates a faulty cable or loose connection.

VOLTAGE REGULATOR Connect the voltmeter between the regulator terminal (A.1) and ground. No reading indicates a faulty regulator.

CABLE (BROWN/BLUE)-REGULATOR TO LIGHTING AND IGNITION SWITCH Connect the voltmeter between the lighting switch terminal (A) and ground. No reading indicates a faulty cable or loose connection. IGNITION SWITCH Connect the voltmeter between the ignition switch (white cable terminal) and ground. No reading indicates a faulty ignition switch.

CABLE (WHITE)-IGNITION SWITCH TO FUSE UNIT A.3 TERMINAL Connect the voltmeter between the fuse unit A.3 terminal and ground. No reading indicates a faulty cable or loose connection.

CABLE (WHITE)-FUSE UNIT A.3 TERMINAL TO IGNITION COIL Connect the voltmeter between the ignition coil terminal (SW) and ground. No reading indicates a faulty cable or loose connection.

IGNITION COIL Connect the voltmeter between the ignition coil terminal (CB) and ground. No reading indicates a faulty ignition coil.

CABLE (WHITE/BLACK)-IGNITION COIL TO DISTRIBUTOR Connect the voltmeter between the distributor terminal and ground. No reading indicates a faulty cable or loose connection.

DISTRIBUTOR Connect the voltmeter across the distributor contacts. If no reading is given, remove the condenser and test again. If a reading is given, the condenser is faulty. If, after carrying out the foregoing tests, the fault has not been located, remove the high-tension cable from the center terminal of the distributor. Crank the engine until the contacts close. Flick the contact breaker lever open while the high-tension cable from the ignition coil is held about 3/16 inch away from the cylinder block. If the ignition equipment is in order a strong spark should be obtained. If no spark is given; it indicates a faulty ignition coil.
