denser) may have welded contacts together. Separate contacts and clean with
equalising file.
2. Governor transfer lever broken or disengaged.
3. Resistor short-circuited.
4. Condenser short-circuited.

MOTOR IDLES AND WILL NOT RUN FAST.
I. Examine governor contacts for corrosion , which will prevent them from closing.
Clean as above.
2. Examine governor brushes and slip rings. Ensure contact.
