COMPONENT TEST

NOTE: An analog-type ammeter should be used.

Power transistor for coil #1 and #4 cylinders.





1. Connect the negative (-) terminal of the 1.5 volt power supply to terminal 3 of the power transistor; then check whether there is continuity between terminal #5 and terminal #3 when terminal #4 and the positive (+) terminal of the 1.5 Volt power supply are connected and disconnected.





NOTE: Connect the negative (-) terminal of the ammeter to terminal #5.

Power transistor for coil #2 and #3 cylinders.





1. Connect the negative (-) terminal of the 1.5 volt power supply to terminal 3 of the power transistor; then check whether there is continuity between terminal #1 and terminal #3 when terminal #2 and the positive (+) terminal of the 1.5 Volt power supply are connected and disconnected.





NOTE: Connect the negative (-) terminal of the ammeter to terminal #1.






1. Measure the resistance between connector terminals 4 and 2 (the coils at the number 1 and number 4 cylinder sides) of the ignition coil. and between terminals 4 and 1 (the coils of the number 2 and number 3 cylinder sides).

Primary resistance: 0.77 - 0.95 Ohms





2. Measure the resistance between the high voltage terminal for the number 1 and number 4 cylinders and between the high voltage terminals for the number 2 and 3 cylinders.

Secondary Resistance: 10.3 - 13.9 K Ohms

CAUTION: Be sure, when measuring the resistance of the secondary coil, to disconnect the connector of the ignition coil.
