(6) Motor resistor, electrical leads, and connector.

FRAME 1

WARNING

Dry cleaning solvent is flammable. DO not use near an

open flame. Keep a fire extinguisher nearby when sol-

vent is used. Use only in well-ventilated places. Fail-

ure to do this may result in injury to personnel and

damage to equipment.

Wipe bracket (1) with electrical leads (2,3, 4, and 5) with cloth dipped in

dry cleaning solvent. Wipe bracket and electrical leads dry.

Inspect five electrical leads (2) for damaged insulation and connectors. Go

to frame 2 if leads are bad.

Check continuity through electrical leads (2) by using an ohmmeter. Place

one ohmmeter lead on end of electrical lead, the other ohmmeter lead on end

of electrical lead's pin. Go to frame 2 if an open circuit is found.

Inspect electrical leads (3, 4, and 5) for damaged insulation and connectors.

Get new leads if leads are bad.

Check continuity through electrical leads (3, 4, and 5) by placing ohmmeter

leads on each end of electrical lead. Get new lead if circuit is open.

Inspect terminal strip (7) and diode holder (8) for cracks and damaged

threads. Go to frame 2 if any are found.

Check motor resistor by placing ohmmeter leads on outer terminals (9 and 10)

of terminal strip (7). Go to frame 2 if circuit is open.
