How do I know if it is compatible?
We recommend checking the SKU/MPN (873770) and Cross Reference list provided above. If your original part number matches any of these, it is a guaranteed fit.
Why does this alternator have a yellow wire?
The yellow wire is the external battery sense wire. By connecting this directly to the battery or battery isolator, the internal regulator can compensate for voltage drops in the charging cables, ensuring your batteries receive the full 14.4V charge.
