the inside face of the cover to remove and fit
the fuses (see illustrations) .
2 To remove a fuse, use the tweezers
provided to pull it out of the holder. Slide the
fuse sideways from the tweezers. The wire
within the fuse is clearly visible, and it will be
broken if the fuse is blown.
3 Always renew a fuse with one of an
identical rating. Never renew a fuse more than
once without tracing the source of the trouble.
The fuse rating is stamped on top of the fuse.
4 With the exception of the indicator flasher
relay, the remainder of the relays are fitted to
the reverse side of the main fuse/relay board.
Access is as described in paragraph 1.
5 The various relays can be removed from
their respective locations on the fuse board by
carefully pulling them from the sockets.
6 The direction indicator flasher relay is
attached to the multi-function switch unit on
the steering column. Access to the relay is
made by undoing the retaining screws and
removing the steering column shrouds. The
relay can then be withdrawn from the switch.
7 If a system controlled by a relay becomes
inoperative and the relay is suspect, listen to
the relay as the circuit is operated. If the relay
is functioning, it should be possible to hear it
click as it is energised. If the relay proves
satisfactory, the fault lies with the
components or wiring of the system. If the
relay is not being energised, then it is not
receiving a main supply voltage or a switching
voltage, or the relay is faulty.
