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 push-
ing RESET button IN.
2
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.
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.
3
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).
