Main Beam

Main Beam

When the column switch is moved to the main beam position, current flows across the switch (C0036-5) to fuse 17 and fuse 18 in the passenger compartment fuse box (C0581-13) on a blue/white wire. Fuse 17 (C0581-14) supplies a feed to the RH headlamp main beam bulb (C0011-1) on a blue/orange wire. The bulb (C0011-3) is earthed on a black wire. Fuse 18 (C0581-16) supplies a feed to the LH headlamp main beam bulb (C0009-1) on a blue/slate wire. The bulb (C0009-3) is earthed on a black wire.

The column switch also provides a feed to the main beam warning lamp in the instrument pack (C0233-1) on a blue/white wire. The warning lamp (C0230-8) is earthed on a black wire.

Headlamp Flash

Fuse 3 of the engine compartment fuse box (C0572-1) supplies a constant battery feed to the column switch (C0036-7) on a brown/purple wire. When the column switch is pulled back to the flash position, it allows current to flow along the main beam circuit as described in the ’Main Beam’ operation.
