Turn Signal Switch: Description and Operation

Voltage is supplied to the RH and LH Snowplow Turn Signal Relays through the Battery Junction Block at all times. When the Turn Signal Switch is placed in LH or RH turn the appropriate relay will energize, providing battery voltage to the associated turn signal on the snowplow assembly. As the turn signal flashes on and off the relay will also cycle on and off, causing the snowplow turn signal lamp to flash.
