1. GENERAL INFORMATION
1.1 FUSES AND CIRCUIT BREAKERS
FUSES
All vehicle electrical circuits are protected against
damage which might occur because of short
circuits or overloads in the wiring system.
Protection is provided by a fuse, circuit breaker, or
fusible link.
Fuses ar e the blade type mini fuse, with the curr ent
rating in amps indicated on top of the fuse
assembly, above the element, or by the colour of
the fuse.
Figure 12N-1
CURRENT RATING
(AMPS) FUSE COLOUR
3VIOLET
5TAN
7.5 BROWN
10 RED
15 BLUE
20 YELLOW
25 WHITE
30 GREEN
To determine whether or not a fuse has blown,
rem ove the suspec t fuse and exam ine the element
in the fuse for a break.
NOTE:
A blown fus e is caused by a fault. Replace a blown
fuse only with a fuse of the same rating. If the
replacement fuse blows, rectify the fault before
replacing the fuse again.
Fuses are located in two positions on VT Series
Models. One group is located in the fuse and relay
panel assembly, inside the vehicle passenger
compartment, behind the instrument panel lower
right hand side cover.
Access to the passenger compartment fuse and
relay panel assembly is by first adjusting the
steering column to it’s upper most position. Then
grasping the right hand side of the ins tr ument panel
lower cover firmly, pull the cover downward. Repeat
the procedure for the left hand side of the cover
and then allow it to swing down.
A label on the inside of the cover indicates the
circuits protected by each fuse, as well as
nominating relay function.
When reinstalling the cover, ensure that the
locating clips are correctly aligned, swing cover up
and ensure that the clips engage into their mating
retainers securely. Figure 12N-2
Fig. 12N-3 illustrates the passenger compartment
fuse and relay panel assembly, nominating fuse
number and each system protected by that fuse.
On vehicles with power operated windows, a 20
amp circuit breaker is installed in the passenger
compartment fuse and relay panel assembly at
fuse c avity F1. An additional 20 amp c irc uit br eaker
is included at fuse cavity F2 for the electrically
adjustable front seat operation.
A circuit break er is a c ircuit protec tion device which
will open circuit when the circuit c ur rent ex c eeds its
rating, and will close again after it cools.
The circuit breaker will continue to open and close
until the cause of the excess current is corrected.
Figure 12N-3
Included in the passenger compartment fuse and
relay panel assembly is a fuse remover. To use,
pull the remover from it’s location in the panel,
insert fully over the top of the fuse to be removed
and then pull fuse from the panel.

FUSIBLE LINKS
The chassis and engine electrical wiring is
protected against short circuit damage by fusible
links contained in engine compartment fuse and
relay panel assembly, situated forward of the right
hand side front suspension strut tower.
The fusible links are a plug in type, with an
inspection window which allows a visual; check of
the fusible link condition.
To determine whether or not a fusible link has
blown, examine the fusible link element for a break.
NOTE:
A blown fusible link in c aused by a fault. Replace a
blown fusible link only with a fusible link of the
same current rating. Fusible link current rating is
indicated on top of the assembly, adjacent to the
inspection window. If the replacement fusible link
blows, rectify the fault before replacing the fusible
link again.
Figure 12N-7
All fusible links c an be r emoved by pulling them out
of their housing sockets, except for the FS 60 A
ENGINE fus ible link and the two engine cooling fan
FT and F U 30 A fusible link s. Removal pr ocedures
for these fusible links are detailed in the
SERVICE OPERATIONS in this Section.
