Power Trim and MerCathode Overload Protection
If an electrical overload on the electrical system occurs, a fuse will open (blow). Find and correct the cause before replacing the
fuse.
NOTE: If you must operate the engine in an emergency, turn off and disconnect all accessories from the engine and
instrumentation wiring in an attempt to isolate the electrical overload or excessive current draw. Replace the fuse. If the fuse
burns out, the electrical overload has not been eliminated and further checks must be made on the electrical system. Contact
your Mercury Diesel authorized repair facility.
