6D5-4 DISTRIBUTORS
• Connect an ohmmeter to either pickup coil lead
1
and the housing as shown in figure 5, step;ij.
The reading should be infinite. If hot, replace
the'coil. -
• Connect an ohmmeter to both pickup coil leads
as shown in figure 5, step 2. Flex the leads by
hand at the coil and the connector to locate any
intermittent opens. The ohmmeter should read
a constant unchanging value in the 500 to 1500
ohm range. If not, replace the coil.

2. Electrical performance of the module. The module
can only be checked with an approved module tes
ter, such as J 24642-F. Follow the directions exact
ly that come with the tester.

•Connect the ohmmeter as shown in figure 6i
step 1. Use the high scale. The reading should
be infinite. If not, replace the coil.
|
• Connect the ohmmeter as shown in step 2. Use
the low scale. The reading should be very loW
(0.35 - 0.45 ohms). If not, replace the coil.

• Connect the ohmmeter as shown jn step 3. Use
the high scale. The meter should read 7,000 to
10,000 ohms. If not, replace the coil.

•Lubricate
• Bottom of the module and the module rest pad
in thd housing with silicone grease or an equiv
alent I heat transfer substance.
1. Ignition module (14) to the housing (30) with two
screws';
2. Pickup poil (11).
• Fit the tab on the bottom of the coil into the
anchor hole in the housing.
3. Pickup coil wiring connector to the module.
• Make sure the locking tab is in place.
4. Shield (50) onto the coil.
5. Retainer (49) onto the shield.
• Use a new round retainer if the center bushing
in the distributor base has no groove around
, the outside (figure 7).
• Use a new square retainer when there is a
groove in the center bushing.
A. Place the retainer over the center bushing with
the teeth pointing upward.
B. Place, a 15-mm (5/8-inch) socket head onto the
edge of the retainer. Keep the socket centered
on the retainer so the teeth are not damaged.
