FUSES AND CIRCUIT BREAKER
A circuit breaker in the light control switch protects
the headlamp circuit, thus eliminating one fuse. A
separate circuit breaker protects the power window,
seat and top circuits. On Corvettes the headlamp motor
circuit is also protected by a separate circuit breaker.
Where current load is too heavy, the circuit breaker
rapidly opens and closes, protecting the circuit until
the cause is found and eliminated.
louses located in the Fuse Panel under the instrument panel are:
Wiper (Chevrolet, Chevelle, and "F" Car) 3AF/AGC 20 Amp.
Back-up Lamp and Gauges. . . 3AG/AGC 10 Amp.
