See Figure 1
- Remove the rotor and pick-up coil leads from the module.
- Using an ohmmeter, attach one lead to the distributor base and the second lead to one of the pick-up coil terminals of the connector, as shown in test 3 in the accompanying figure.
- The reading should be infinite. If not, the pick-up coil is defective.
- Attach both leads of the ohmmeter to the pick-up terminal ends of the connector, as shown in test 4 in the accompanying figure.
- The reading should be a steady value between 500-1500 ohms.
- If the reading is not within the specifications, the pick-up coil is defective.
While testing, flex the leads to determine if wire breaks are present under the wiring insulation.
REMOVAL & INSTALLATION
See Figures 2, 3, 4 and 5
- Disconnect the negative battery cable.
- Remove the distributor from the vehicle. For details, please refer to the procedure later in this section. Remove the cap and rotor.
- Matchmark the gear and shaft for installation purposes, then drive the roll pin from the gear and pull the shaft assembly from the distributor.
- Unfasten the 3 retaining screws, then remove the magnetic shield from the distributor.
- Remove the thin "C" washer (waved retaining ring), then lift the pick-up coil straight up to remove from the distributor.
- Remove the magnet and pole piece.
- Install the pole piece and magnet.
- Install the pickup coil and the thin "C" washer.
- Assemble the shaft, gears parts and roll pin. Use the marks made during removal for alignment purposes.
- Spin the distributor shaft to be sure the teeth do not touch. If the teeth make contact, loosen, then re-tighten the pickup coil teeth and Hall Effect Switch teeth (if used) to eliminate contact.
- Install the rotor and cap, then install the distributor assembly. For details, please refer to the procedure located later in this section.
- Connect the negative battery cable.
