Primary Coil And Ignition Power Transistor Continuity Check

WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

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.

As described in the chart below, perform a continuity check on the ignition coil power transistor.
