Qualitypower1 StoreThis is aGM Chrome 100 Amp Replacement Alternator.These 1-wire alternators require only the battery charge cable (1-wire) to be hooked up to the output post at the rear of the unit. Install the alternator, start the vehicle, and step on the gas slightly and the alternator will start to charge on its own. This is the easiest installation possible! We build these units to provide 55 amps at an idle. That's as much as the original units put out at high RPM. This alternator will replace externally and internally regulated alternators from 1963 through1983 year models. Also perfect for street rods and project cars.See our store for special brackets to use this alternator to replace generators, for flathead Ford conversions, and Chrysler OEM alternator replacements.Please visit our Quality Power eCRATER StoreEMAIL US IF YOU HAVE A QUESTIONWANT TO PICKUP LOCALLY - NEED DIRECTIONS?
