INSPECTION AND
ELECTRICAL TESTS
Inspect
Cap for cracks or tiny holes. Replace the cap if it is
damaged at all.
Metal term inals in the cap for corrosion. Scrape them
clean with a knife or replace the cap.
Rotor for wear or burning at the outer term inal. The
presence of carbon on the term inal indicates rotor
wear and the need for replacement.
Shaft for shaft-to-bushing looseness. Insert the shaft
in the housing. If the shaft wobbles, replace the hous
ing and/or shaft.
Housing for cracks or damage.
Measure
Tools Required:
J 24642-F Module Tester
Voltage of the Hall Effect switch (if equipped).
• C onnect a 12 volt battery and voltm eter as
shown in figure 17.
• With a knife blade inserted and held against the
magnet, the voltm eter should read within 0.5
volts of the battery voltage. If not, replace the
switch.
• Remove the knife blade. The voltm eter should
read less than 0.5 volts. If not, replace the
switch.
Resistance of the pickup coil with an ohm meter.
• Connect an ohm m eter to either pickup coil lead
and the housing as shown in figure 27, step 1.
The reading should be infinite. If not, replace
the coil.
• Connect an ohm m eter to both pickup coil leads
as shown in figure 27, step 2. Flex the leads by
hand at the coil and the connector to locate any
interm ittent opens. The ohm m eter should read
a constant unchanging value in the 500 to 1500
ohm range. If not, replace the coil.
Electrical perform ance of the module. The module
can only be checked with an approved module tester,
such as J 24642 or equivalent. Follow the directions
exactly that come with the tester.
Resistance of the ignition coil with an ohm meter.
• C onnect the ohm m eter as shown in figure 28,
step 1. Use the high scale. The reading should
be infinite. If not, replace the coil.
• Connect the ohm m eter as shown in step 2. Use
the low scale. The reading should be very low or
zero. If not, replace the coil.
• Connect the ohm m eter as shown in step 3. Use
the high scale. The meter should not read infi
nite. If it does, replace the coil.
