Power Transistor

COMPONENT TEST

NOTE: An analog-type ohmmeter 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 ohmmeter 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 ohmmeter to terminal #1.
