Remove and Replace

Must remove

wires through

column

When routing wires must be careful


Turn signal circuits

R & R Combination Switch


Cornering lights

CORNERING LIGHTS

  • Turn Signal Activated

    • All the time

    • Night time only

  • Will Stay on until Flasher Turns Signal Light on again

  • Some systems have extra contacts inside turn signal switch

C281 to C283


Turn signal circuits

CORNERING LIGHTS PARKING AND TAILLIGHTS

  • Two Bulb System

    • Relay controlled

  • Three Bulb System

  • Some systems powered through headlight switch and by battery

  • Other systems powered by turn signal switch


Parking lights off turn signal on

Parking lights off / turn signal on

  • Marker light receives power from turn signal switch

  • Ground for side marker through park light filament

  • Side Marker will flash with turn signal light

Page C287


Parking lights on turn signal off

Parking lights on / turn signal off

  • Marker light receives power from park lights circuit

  • Ground for side marker through turn light filament

  • Side Marker will come on with park lights


Turn signal on park lights on

Turn Signal On / Park Lights On

  • Voltage equal to both sides of Marker Light

  • Flasher turns off Turn Signal Light then Turn filament is ground for Marker Light

  • Will Stay on until Flasher Turns Signal Light on again


Turn signal on parking light on

Turn Signal on / Parking Light On

  • Wired parallel with with parking lights.

  • high resistance side marker light bulb

  • ground through turn signal filament

  • turn signal filament less resistance than side marker filament

Is this drawing correct?
