When the switch (C113) is in position 1 power supply to the
work lights is isolated (work lights OFF).
24V is supplied by Fuse 24 on the main fuse module (C100

When the switch is in position 2 - a 24V supply exits via pin
3 where is it is distributed to the boom working lights
(C124, C162) and the DECU (C109 J1, pin 1) The DECU
activates warnings if the work lights are ON after 15
seconds if the engine is not running. Power is also
connected to the LED (C147) to allow back lighting and
illumination of the console.

as position 2 plus supplies 24V to pin 5. Pin 5 is the supply
to the counterweight light (C125).
