RADIO INTERFERENCE SUPPRESSION. Stray electrical currents must be prevented from
building up between components and wiring harnesses to eliminate radio interference. Stray
currents, if allowed to build up and spark (arc to a ground), will cause noise in, and possibly
disrupt, radio communications.
Electrical currents can also produce signals that may
interfere with vehicle equipment sensitive to small changes in power or, in extreme cases,
give off signals strong enough to give away location. Interference is eliminated by providing
low resistance paths to ground for stray currents and by using shielded wiring.
Low
resistance components include capacitors, tooth-type lockwashers, grounding springs, and
