Ignition Power Transistor

NOTE:
An analog-type circuit tester should be used.

[1][2]Ignition power transistor for coil for No.1 and No.4 cylinders.
- Connect the negative (-) terminal of the 1.5V power supply to terminal 3 of the [1][2]ignition power transistor; then check whether there is continuity between terminal 3 and terminal 2 when terminal 7 and the positive (+) terminal are connected and disconnected.
