2. Ignition System High-Voltage Damper Testing (see gure 17)
(1) Move the connectors of the ignition system from the engine. Refer to the ignition
system movement procedure in various kinds of automotive manuals for the details.
Warning:
Some of Chrysler’s products use a spark plug high voltage damper with “positive
lock” end electrodes, which can only be moved out of the distributor board. If it is
moved out of anywhere else, some damage will result. Refer to various kinds of
automotive manuals for the details.
(2) Set the rotary switch to the Ω. Insert the red test lead into the Ω terminal and the black
one into the COM terminal.
(3) Connect the red and black test lead probes in parallel to the two ends of the high-
voltage damper and observe the reading. The normal resistance is generally in a
range of 3 kΩ to 50 kΩ. In bending the lead, the reading should remain unchanged.
