1. ROOF-MOUNTED HIGH-BEAM HEADLIGHTS
A constant voltage is applied through wire 1000
(voltage before contact) and fuse E084 to
connection point 7 of switch C775 (dipped
beam/main beam switch). If the main beam is
switched on (connection between points 7 and
6), a voltage is applied to main beam relay
(G002). Once the relay is activated, a
connection is made between points 30 and 87.
As a result, a voltage is applied through fuse
E007 and wire 2123 to connection point 6 of
roof-mounted high-beam light switch (C813). If
the switch is operated, voltage is applied to
roof-mounted high-beam headlight relay (G299)
as well This relay is energised. Now voltage is
applied through fuse E168 (in overhead box),
wire 1175 (on Pertinax block) (in overhead
box)), and through fuse E188, wire 2134 to
contacts 3 and 1 of roof-mounted high-beam
headlight relay (C299). A voltage is also applied
to the high-beam headlights through wire 2135.
