Replacing Relays
Before replacing relays, remove the cover.
ADVICE
• It is not necessary to open or close the cover unless trouble is found.
• The relay box structure makes it difficult for water to enter. If you should spill
water or a beverage on the cover, however, wipe it off before opening the cover.
• The area around the cover will get warm when the vehicle is being driven, but
this is not abnormal.
Replacing Slow-blow Fuses
When the headlights and other devices in the electrical system do not work, but there
is no problem with the fuses, check the slow-blow fuse.
Replace the slow-blow fuse when it blows. Please contact the nearest Isuzu Dealer.
Slow-blow fuses protect the electrical circuits, and they are installed so that they can
be quickly replaced if there is a malfunction.
WARNING
• Use an Isuzu genuine part when replacing the slow-blow fuse.
• Do not use any material other than designated slow-blow fuses. Using other
materials could cause a serious malfunction or fire.
• If the new slow-blow fuses blow right away, contact the nearest Isuzu Dealer.
NOTE
• If an overload exists in the circuit from the battery, the slow-blow fuse will melt
before the wiring harness is damaged.
