11 FUEL HEATER When Slow-blow Fuses Blow Out
Slow-blow fuses protect the
electrical circuits, and they are
installed so that they can be quickly
replaced if there is a malfunction.
If an overload exists in the circuit
from the battery, the slow-blow fuse
will blow out before the wiring
harness is damaged to protect the
electrical circuitry. InspectionWhen 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.
The slow-blow fuse is blown if it
looks like the illustration.
Immediately contact the nearest
dealer.
