TERMINAL 1 CONNECTOR OHMMETER PICKUP COIL LEADS DIS. 2 1. A typical distributor used with a separately mounted coil CONNECTED s shown. OHMMETER FROM MODULE TESTING IGNITION COIL 3. Remove rotor and pickup coil leads from module. IGNITION COIL 4. Connect ohmmeter Part I and Part 2. 5. If vacuum unit is used. connect vacuum source to vac uum unit. Replace vacuum unit if inoperative. 6. Observe ohmmeter throughout vacuum range: if no vac- uum unit is used. flex leads by hand to check for intermittent opens. Step 1 - Should read infinite at all times. If not, pickup coil is defective. Step 2 - Should read one steady value between 500- 1500 ohms as vacuum is operated, or as leads are flexed by hand. If not, pickup coil is defective. 7. Ohmmeter may deflect if operating vacuum unit cause teeth to align. This is not a defect. DRIVING PIN FROM SHAFT 1 2 3 OHMMETER OHMMETER OHMMETER 2. Check ignition coil with ohmmeter for opens and grounds: Step 1. - Use high scale. Should read very high (infi- ROLL nite). If not. replace coil. PIN- Step 2. - Use low scale. Should read very low or zero. If 8. If distributor has a Hall Effect Switch (identified in Step not. replace coil. 12), remove this switch by detaching screws. Then drive roll pin Step 3. - Use high scale. Should not read infinite. If it from gear and remove shaft assembly. Mark gear and shaft for coil rrect reassembly.
