FUSES AND BULBS
Fuses and circuit breakers protect the electrical wiring in the
car against overloading. All fuses are contained in a fuse panel
located behind the lower left side of the instrument panel,
except the Guide-Matic fuse, the blower motor fuse on air
conditioned cars, and the seat warmer fuse. See fuse chart
for location of these fuses and all circuit breakers.
Fuses can be easily replaced by releasing the locking lever
on the left side of the fuse panel and moving the panel down
far enough to permit tabs to be free of locking lever. Then
move fuse panel forward through notch in bracket and pull
panel downward as far as wires permit.
Specifications for fuses and bulbs are listed in two charts.
Replacement parts should be of same type and capacity
characteristics as those listed.
