Ignition Power Transistor
- Disconnect connector at ignition power transistor. Ignition power transistor is mounted on top of engine, near ignition coil and contains a 8-pin Black connector.
- To check ignition power transistor for cylinders No. 1 and 4, connect analog type ohmmeter between terminals No. 3 and 8 of ignition power transistor. See Fig 1
.
- A 1.5-volt battery will be used as the power supply. Connect negative terminal of a 1.5-volt power supply to terminal No. 3 of ignition power transistor. See Fig 1
.
- Momentarily touch positive terminal of 1.5-volt power supply to terminal No. 7 of ignition power transistor. Continuity should exist between terminals No. 3 and 8 of ignition power transistor when positive terminal of 1.5-volt power supply is connected to terminal No. 7.
- Disconnect positive terminal of 1.5-volt power supply from terminal No. 7 of ignition power transistor. Continuity should no longer exist between terminals No. 3 and 8 of ignition power transistor. Replace ignition power transistor if continuity is not as specified.
- To check ignition power transistor for cylinders No. 2 and 3, connect analog type ohmmeter on between terminals No. 1 and 3 of ignition power transistor. See Fig 2
.
- Connect negative terminal of a 1.5-volt power supply to terminal No. 3 of ignition power transistor. See Fig 2
.
- Momentarily touch positive terminal of 1.5-volt power supply to terminal No. 2 of ignition power transistor. Continuity should exist between terminals No. 1 and 3 of ignition power transistor when positive terminal of 1.5-volt power supply is connected to terminal No. 2.
- Disconnect positive terminal of 1.5-volt power supply from terminal No. 2 of ignition power transistor. Continuity should no longer exist between terminals No. 1 and 3 of ignition power transistor. Replace ignition power transistor if continuity is not as specified.
