Electrical System Overload Protection
If an electrical overload occurs, a fuse will blow or the circuit breaker will trip open. The cause must be found
and corrected before replacing fuse or resetting circuit breaker.
1 A circuit breaker provides protection for engine wiring harness and instrumentation power lead. Reset by
pushing RESET button IN.
A Carburetor Models
B EFI Models
In an emergency, when engine must be operated and cause for high current draw cannot be located and
corrected, turn OFF or disconnect all accessories connected to engine and instrumentation wiring. Reset circuit
breaker. If breaker remains open, electrical overload has not been eliminated. Further checks must be made on
electrical system.
2 On EFI Models: A 90 Amp fuse is located on the large post of the starter solenoid. This fuse is designed to
protect the engine wiring harness if an electrical overload occurs.
3 On EFI Models: There are three fuses located in the fuel injection system electrical box. These fuses control
various EFI circuits.
A Fuel Pump Fuse - 15 Amp
B ECM / Injector Fuse - 10 Amp
C ECM / Battery Fuse - 15 Amp
4 A 20 amp fuse may be located in ignition switch “I” terminal lead to protect electrical system. Check for blown
fuse if key is turned to START and nothing happens (and circuit breaker is not tripped).
