General Methods Used to Attain Proper Suppression. Essentially,

suppression is attained by providing a low-resistance path to ground

for the stray currents.

The method used to attain suppression in-

elude shielding the ignition and high-frequency wires, grounding the

frame with bonding straps, and using capacitors and resistors where

necessary.

Interference Suppression Components.

(A) A 0.5 MF (Micro Farad) capacitor is mounted on battery

terminal of regulator.

(B) A 0.5 MF (Micro Farad) capacitor is mounted on generator

terminal of generator.

(C) A wave trap is mounted on field terminal of generator.

(D) Regulator and rear half of generator are encased in

metal housing.

(E) Generator is grounded directly to chasis by means of a

ground strap attached from generator ground screw to

ground bolt.

(F) Test stand is grounded directly to positive ground by

means of ground bolt located on chasis just forward of

hose connectors.

Testing

Radio Interference Suppression Components. Test the

capacitors for leaks and shorts on a capacitor tester.

Replace

a defective capacitor.

If test equipment is not available and

interference is indicated, isolate the cause of interference by

trial and error method or replace each capacitor in turn until the

cause of interference is determined and eliminated.
