Continuity Test
The continuity test accessory cable is used in conjunction
with the meter on the Tester. A high meter reading indicates
an open circuit (no continuity) while a zero meter reading
indicates continuity.
When you make a continuity test, keep the following
points in mind:
1. Make sure a regulator is not installed in the holder.
2. The knob is turned clockwise only until it clicks.
3. All components must be isolated for testing.
4.
Make sure voltage is not applied to the component
being tested.
SLIP RING SERVICING
If the slip rings are dirty, they may be cleaned and
finished with 400 grain or finer polishing cloth. Spin the
rotor, and holding the polishing cloth against the slip rings
until they are clean.
CAUTION: The rotor must be rotated in order
that the sf@ rings will be cleaned evenly. Cleaning
the slip rings by hand without spinning the rotor
may result in flat spots on the slip rings, causing
brush noise.
