In an emergency, if you cannot locate and correct the cause of the high

current draw, and you must operate the engine; perform the following:
1. Turn "OFF" or disconnect all accessories connected to the engine and

instrumentation wiring and reset the circuit breaker.

2. If the breaker remains open, electrical overload is still present. Inspect

the electrical system.

The power trim system is protected by a 10 amp fuse in the power trim RED

(Hot) wire.
