An indicator that is on when ever power is applied to the trim motor. 2. A guarded trim cutoff switch to remove power from the trim motor in the event the trim indicator is on when trim is not being commanded. 3. An alternate power source and alternate trim switch isolated from the primary in the event of a primary trim system failure. Just like the big iron.
