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 replac-
ing 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 an emergency, when engine must be operated and cause for high
current draw cannot be located and corrected, turn OFF or discon-
nect all accessories connected to engine and instrumentation wiring.
Reset circuit breaker. If breaker will not reset, electrical overload has
not been eliminated. Further checks must be made on electrical sys-
tem.
2
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).
3
The Power Trim System is protected from overload by 110 amp
fuse and a 20 amp in-line fuse on Power Trim pump.
4
Quicksilver Three-Button Power Trim Control Panel is further pro-
tected by a 20 amp in-line fuse.
