ROTOR RESISTANCE TEST (continued)
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 bail.
3. Remove the fuel cap. The rubber gasket for the
fill tube will come off with the case top.

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 4 and 5 ohms.
