Fuses and relays

The fuse box is located under the dashboard on the
vertical face of the engine bulkhead (see illustration
below). Although the fuses and relays are not
numbered the tables below are in the order that
they will be found in the fuse box working from the
top down.
Figure 23: Fuse box and relay location
Fuses are simple circuit breakers, which protect
electrical equipment by preventing the electrical
circuits from being overloaded. A 'blown' fuse is
indicated when the electrical equipment it protects
becomes inoperative. Check a suspect fuse by
removing it from the fuse box and looking for a
break in the wire inside the fuse.

Renewing a fuse

Always turn off the ignition switch and the
appropriate electrical circuit before removing a
fuse. Always replace a fuse with another of the
same (or lower) rating. If a replacement fuse blows
almost immediately, this indicates a serious
electrical problem and the circuit MUST be checked
by Caterham.

Fuse colours

The fuses are colour coded to identify their
amperage ratings as follows:
ORANGE
BROWN
RED
BLUE
YELLOW
