Cigar Lighter Supply
Circuit supply
A feed from the battery positive terminal is connected by a R wire to the engine compartment fusebox where it passes to fusible link 8 and fusible links 1
and 7 which are connected in series. The feed from fusible link 7 is connected to the auxiliary circuits relay mounted in the engine compartment fusebox.
The feed from fusible link 8 is connected to the passenger compartment fusebox on an NW wire and from the fusebox to the ignition switch on an N
wire.
Ignition switch supply
When the ignition switch is in position I or II, the feed from fusible link 8 flows through the ignition switch) to the passenger compartment fusebox on an
LGW wire. The feed continues through fuse 26 and is connected by an LG wire to the auxiliary circuits relay. The feed passes through the auxiliary relay
coil and is connected to earth header C0018, via header C0285 LHD/C0288 RHD on a B wire.
The auxiliary circuits relay is energised which closes the relay contacts. This allows the feed from fusible link 7 to pass through the relay contacts to the
passenger compartment fusebox on a WG wire. The feed then passes through fuse 15 and is connected, through header C0286 LHD/C0291 RHD to the
cigar lighter on an LGW wire. The cigar lighter is connected through header C0286 LHD/C0288 RHD to earth header C0018 on a B wire.
