Section 2 - Getting to Know Your Power Package
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
Cummins MerCruiser Diesel Authorized Repair Facility.
