ROTOR RESISTANCE TEST (continued)

 

13.Measure the resistance to ground.

A.Set the ohmmeter on the high scale (X100,000).

B.Place one probe on either of the slip rings. Place the other probe on any good, unpainted ground. The machine ground stud works well.

C.Check the resistance. It should read very high, at least 0.5 megohm (500,000 ohms).

If the test does not meet the resistance speci- fications, then the rotor may be faulty. Replace the rotor.

If the test does meet the resistance specifica- tions, then the rotor is okay.

14.Connect lead 200A to the positive brush, which is the one nearest the rotor lamination. Connect lead 219 to the negative brush.

15.Reinstall the case side, case top, fuel cap, lift bail gasket and spark plug wires.
