Confirm the correct fuse location, inspect the surrounding wiring and terminals for heat damage or corrosion, and repair any electrical fault before installing the replacement fuse assembly. Use the correct OEM amperage only; do not bypass the fuse or substitute a higher-rated part.\u003c\/p\u003e\n\u003ch2\u003eAlternate \/ Superseded Part Numbers\u003c\/h2\u003e\n\u003cp\u003eThe active Mercury OEM part number for this listing is \u003cstrong\u003e79023T10\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eRelated references may appear with Mercury prefix formatting, including:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e79023T10\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e88-79023T10\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eParts Desk Insight\u003c\/h2\u003e\n\u003cp\u003eThe important check with a fuse assembly is \u003cstrong\u003ewhy the original fuse failed\u003c\/strong\u003e.
