SECTION III: PRINCIPLES OF OPERATIONTM 9-2350-256-203 Personnel heater. The personnel heater fuel pump is integrally suppressed by means of a feedthrough capacitor. A0.25-mfd, 100-V dc, 20-A, feedthrough capacitor mounted on the motor housing is in series with the blower motorpositive power input lead.4 Ventilating blower. A 0.1-mfd, feedthrough capacitor mounted in the motor housing is inserted in series with the powerinput lead of the blower. The power input lead between the blower and input power connector is also shielded withbraided cable.5 Roadwheels, track support rollers, and idler wheels. Static grounding springs are included in the roadwheels and tracksupport rollers. These coil steel springs function as grounding devices for static electricity developed by the wheelsand rollers when the vehicle is in motion.b. OTHER MEANSFeedthrough capacitors require good bonding or grounding to provide adequate radio noise suppression. Tinnedcopperbraid bond straps, terminated in appropriate copper lugs and bonded by means of plated tooth-type lockwashers,are used for this purpose when good contact between the component to be suppressed and ground is required. Whereclearance is not a problem and the component is mounted with bolts or other fasteners, plated tooth-type lockwashersare used to provide the grounding.1-37 (1-38 blank)
