TESTING - CONTINUED
Use ohmmeter set to lowest range to test three positive
diodes (30) and negative diodes (31). Touch one test
wire to the diode casing and the other wire to the ter-
minal on the diode wire, then switch test wires. Meter
should indicate one high and one low reading. Replace
diode if readings are the same.
CLEANING AND INSPECTION
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low toxic
material. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in
well-ventilated areas. Keep away from open flames and other sources of ignition.
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle pressure
when drying parts with compressed air. Use a maximum of 30 psi (207 kPa) when cleaning compo-
nents. DO NOT direct compressed air against human skin. Failure to follow this warning may result in
serious injury or death. Make sure air stream is directed away from user and other personnel in the area.
To prevent injury, user must wear protective goggles or face shield.
Remove all gasket material from mounting surfaces.
Clean all parts with solvent.
Dry all part with compressed air.
Inspect all parts for damage and replace as necessary.
