REPLACING FUSES
CAUTION
The fuses protect the electric circuit against
overcurrent. Use fuses of the specific ampere
rating.
Check to see that the components in each circuit are
operating properly. If every component in a circuit is not
functioning, it indicates that the corresponding fuse is
blown out. Replace the blown fuse with a spare fuse of
the same capacity and color.
If some of the components in a circuit do not function
properly, it suggests that a bulb has burnt out. Replace
the burnt bulb with a new one of the same capacity.
①②③④
: They function regardless of the key
switch position.
⑤⑥⑦⑧⑨⑩
: They function when the key switch is in
“ON”.
FUSIBLE LINK (MAIN FUSE)
As the main fuse for the entire truck, a fusible link is
provided at the positive (+) side of the battery. If the
entire electrical circuit of the truck does not function,
replace this fusible link with a new one.
If replacement of the fusible link is needed, the cause of
blowout should be located and troubleshooted properly.
Consult your local UniCarriers dealer.
