The 1965 Mustang was the first to have an alternator. It put out 45 amps (give or take an electron), more than adequate for the car’s minimal electrical demands. But those 45 amps are outgunned in a Mustang upgraded with a hot ignition system, multi-gigawatt entertainment systems, halogen headlights, and other modern conveniences.

Summit Racing’s 100 Amp Alternator will generate enough juice to feed your Mustang’s hungry electricals, it also has a simple one-wire hookup to help tidy up your engine compartment.

What It is: Summit Racing 100 Amp Alternator for 1964 1/2 to 1970 Mustang.

Why It’s Cool: 100 amps output and one-wire hookup. The alternator features a GM 10si case with Ford mounting points, making it a direct swap for the factory alternator. All of the internals are brand new, not remanufactured.
