Electrical System Overload Protection-Carbureted Engines - Mercury MerCruiser Tow Sport 5.7 LHS Manual

Section 2 - Getting to Know Your Power Package
Electrical System Overload Protection—Carbureted Engines
If an electrical overload occurs, a fuse will open or the circuit breaker will open. The cause must be found and corrected before
replacing the fuse or resetting the circuit breaker.
NOTE: In an emergency, when the engine must be operated and the cause for the high current draw cannot be located and
corrected, turn off or disconnect all accessories connected to the engine and instrumentation wiring. Reset the circuit breaker. If
the breaker remains open, the electrical overload has not been eliminated. Further checks must be made on the electrical
system. Contact your authorized dealer as soon as possible.
1. A circuit breaker provides protection for the engine wiring harness and the instrumentation power lead. Reset the circuit
breaker by pushing the red button.
2. A 90‑amp fuse located on the large post of the starter solenoid, protects the engine wiring harness if an electrical overload
occurs.
3. A 15‑amp accessory fuse is located on the rear of the engine. This fuse protects the accessory circuits.
