2) Cleaning Slip rings 

The slip ring surfaces must be uniformly 

bright. Slip rings showing black spots, 

excessive wear, or uneven wear must be 

repaired. A stained slip ring lowers generator 

efficiency and output voltage. Polish the 

slip rings with fine sandpaper while turning 

the rotor until rough spots disappear. Care 

should be taken not to touch the rotor coils 

with the sandpaper. 

 

8-2 AC VOLTAGE IS TOO HIGH OR TOO LOW 

8-2-1 CHECKING ENGINE SPEED 

If the engine speed is too high or too low, 

adjust it to the rated r.p.m. 

 

[How to adjust engine r.p.m.] 

* Loosen the lock nut on the adjusting screw. 

* Turn the adjusting screw clockwise to 

decrease engine speed or counterclockwise 

to increase engine speed. 

 

 

 

 

 

 

 

8-2-2 CHECKING STATOR 

Check stator referring to Step 8-1-1. 

 

8-2-3 CHECKING ROTOR 

Check rotor referring to Step 8-1-2.
