COMBINATION TAIL AND STOPLIGHTS (2)

TM 5-2420-222-20-1

LIGHT ELECTRICAL CIRCUITS - CONTINUED

Positive terminals of sockets connected by wires i separate circuits to light switch TL terminal and brake light

pressure switch negative terminals.

Negative terminals of each socket grounded to housings.

Provide rear marking for night operation's when light switch lever is in third (H1) or fourth (H2) position.

Indicate stop when ignition lock switch is on and brakes are applied.

TURN SIGNAL SWITCH IN-LINE FUSE

One end connected by wire through positive side of 20 ampere circuit breaker to ignition lock switch ACC terminal.

Other end connected by wire to warning light flasher X terminal.

14 ampere quick-blowing glass fuse protects warning light flasher, turn signal switch, and warning light and

combination tail and floodlight taillight circuits.

WARNING LIGHT FLASHER

X terminal connected by wire to turn signal switch in-line fuse.

P terminal connected by wire to turn signal switch unused circuit input.

L terminal connected by wire to turn signal switch operating circuit input.

Provides on-off electrical pulse to flash warning lights and combination tail and floodlight taillights when Ignition

lock switch is on and turn signal switch side buttons are pushed in.

TURN SIGNAL SWITCH

Operating circuit input connected by wire to warning light flasher L terminal.

Unused circuit input connected by wire to warning light flasher P terminal.

Operating circuit outputs connected by wires in common circuits to warning lights and combination tail and

floodlight taillights.

Allows operator to operate warning lights and combination tail and floodlight taillights as turn signals or warning

flashers.

WARNING LIGHTS (2)

Positive terminals of sockets connected by wires in common circuits with circuits of combination tail and floodlight

taillights.

Negative terminals of sockets grounded through housings.

Flash at same time as combination tail and floodlight taillight lamps when ignition lock switch Is on and turn signal

switch side buttons are pushed in.

COMBINATION TAIL AND FLOODLIGHTS (2)

Positive terminals of floodlights connected by wires to light switch FL terminal.

Positive terminals of taillight sockets connected by wires in circuits common with warning lights to turn signal

switch output terminals.

Negative terminals of each taillight socket and floodlight grounded to housings.

Floodlights light up wide area behind loader backhoe for earthmoving operation's at night when light switch lever is

in second (F) position.

Taillight lamps flash through red window in floodlight reflector at same time as warning lights when Ignition lock

switch is on and turn signal switch side buttons are pushed in.
