CAPACITOR
Capacitor — Set ohmmeter at R x 1K.
Slip a heavy piece of paper between points.
Discharge capacitor by touching the two termi-
nals with the blade of an insulated handle screw-
driver.
■
Attach one probe to each terminal; ohmmeter
needle should move rapidly to right then
slowly drift to the left. (Low ohm reading to
high ohm value).
■
If a digital meter is used, readings should
start low and rapidly increase to maximum
value.
■
Replace capacitor if bad.
SWITCH
Remove paper and attach one lead to each
switch terminal. Ohmmeter reading should be 0.
Flip governor weight to running position.
Reading should be infinity.
