Primary Coil And Ignition Power Transistor Continuity Check

Fig 1: Checking Continuity Between Primary Coil And Ignition Power Transistor Using Ohmmeter

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 4.5 - 9.0 V battery between terminal No. 2 and No. 3, and observe the ohmmeter whether there is continuity or not.
2. If results do not agree with the table below, replace the primary coil and ignition power transistor assembly.
