Power Trim and MerCathode Overload Protection
If an electrical overload on the electrical system occurs, a fuse will burn out (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 if you cannot find and correct the cause for the electrical overload or excessive current draw. Replace
the fuse. If the fuse burns out, the electrical overload has not been eliminated. Further checks must be made on the electrical
system. Contact your Mercury Diesel authorized repair facility.
