Primary Coil and Ignition Power Transistor Continuity Check







PRIMARY COIL AND IGNITION POWER TRANSISTOR CONTINUITY CHECK

NOTE: An analog-type ohmmeter should be used.

NOTE: Connect the negative probe of the ohmmeter to terminal 1.

CAUTION: This test must be performed quickly (in less than 10 seconds) to prevent coil from burning and ignition power transistor from breaking.

1. Connect and disconnect 1.5 V battery between terminals 2 and 3, and observe the ohmmeter whether there is continuity or not.
2. If results do not agree with the table, replace the primary coil and ignition power transistor assembly.
