A. Turn the test selector to the OHMS CALIBRATION page in the beginning of
this manual and calibrate the LOW OHMS scale.
NOTE: Make sure the ignition switch is in the OFF position before proceeding.
B. Connect the test clips across the ballast resistor (on CHRYSLER vehicles two
tests must be made: the coil side of the ballast resistor and the module side of
the ballast resistor).
C. Observe the LOW OHMS scale.
RESULTS: | OHMS MORE THAN SPECIFICATIONS — Defective ballast resistor.
REPLACE
OHMS WITHIN SPECIFICATIONS — Ballast resistor is OK.
SPECIFICATIONS: CHRYSLER - Coil side is 0.5 OHMS and module side is 5.0 OHMS;
