TEST PROCEDURE

1.With the 5/16” nut driver, remove the 6 sheet metal screws from the case top.

2.Remove the rubber gasket (cover seal) from the lift bale.

3.Remove the fuel cap. The rubber gasket for the fill tube will come off with the case top.

4.Remove the case top, then replace the fuel cap.

5.With the 5/16” nut driver, remove the 5 screws holding the right case side.

6.Remove the right case side by lifting up and out.

7.Conduct the test with the gasoline engine OFF.

8.Remove the spark plug wires to prevent accidental engine kickback or starting.

9.Isolate the rotor electrically by removing the generator brush leads. Refer to Figure F.2 as you perform the remaining steps.

10.Remove lead #219 from the negative brush.

11.Remove lead #200A from the positive brush.

12.Measure the resistance across the rotor slip rings.

A.Set the ohmmeter on the low scale (X1).

B.Place one meter probe on one of the rotor slip rings. Place the other probe on the other slip ring.

C.Check the resistance across the slip rings. It should read between 7 and 8 ohms.
