Alternator Part Numbers 680175620847, 8600365 Key benefits Reliable 50 amp output for steady battery charging and consistent electrical system performance. Solid pulley design to improve conversion rates and deliver more efficient power transfer to the vehicle drive system. Internal fan reduces exposure to external debris while providing cooling inside the housing. Compact spool mount and negative polarity make installation straightforward where this configuration is required. M81.25 B plus terminal and blade F terminal provide clear, serviceable electrical connections. What this unit does This alternator converts mechanical energy into electrical energy to charge the battery and power onboard electrical systems. It is rated at 50 amperes and is built with a negative polarity configuration and spool mount for direct fit where specified. Technical specifications Part numbers: 680175620847, 8600365 Amperage: 50 A B plus terminal: M81.25 F terminal: Blade Fan: Internal Mount type: Spool Polarity: Negative Pulley: Solid to improve conversion rates Item description: Alternator Why customers need this alternator Restores charging capability in vehicles or machinery that require a 50 amp alternator with a negative ground system. Solid pulley and internal fan help maintain efficient operation and reduce external maintenance needs. Standard terminal types simplify electrical connections and replacement procedures. Compatibility and fit guidance Intended for applications that accept a spool mount alternator with M81.25 B plus terminal and a blade style F terminal. Confirm vehicle or equipment electrical requirements match the 50 amp output and negative polarity before installation. Use the listed part numbers 680175620847 and 8600365 to verify fit against OEM or equipment manuals. Practical use scenarios Replacing a failed alternator on light utility equipment where the original unit used a spool mount and internal fan for protection. Upgrading or restoring charging capability on a small vehicle or generator that specifies a 50 amp alternator with M8 B plus terminal and blade F terminal. Field service replacement in fleet vehicles that require a compact alternator with a solid pulley for reliable power conversion. Installation notes Ensure battery is disconnected before removal and installation. Verify wiring harness terminal types match M81.25 for the B plus connection and blade style for the F terminal. Check belt alignment and tension when installing the solid pulley to prevent premature wear. This alternator provides a practical, specificationdriven replacement option for systems that require a 50 amp negative polarity unit with spool mount, internal cooling, and solid pulley performance.
