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.
