TEST OR INSPECTION
ENGINE DOES NOT START BUT TURNS OVER (Continued)
a. Remove the spark plug wire and test it with a volt-ohmmeter.
Attach a meter lead to each end of the spark plug wire.
If the meter reads below 40 k ohms (40,000), go to Step 6.
If the meter reads steadily above 40 k ohms, replace the wire and go to Step 5b.
Wiggle the wire back and forth. If the meter fluctuates up and down, there is a break in the wire.
Replace the wire and go to Step 5b.
b. Start the engine.
If the engine starts, the problem is solved.
If the engine does not start, go to Step 6.
Step 6. Check the coil.
Figure 5-31. Breaker Point Cover

Remove the spark plug wire from the coil and check the connections for moisture.
connections are wet, dry them and return the wire to the coil. Go to Step 6e.
