This is a new 250 Amp 1-Wire Alternator. All you need to do is connect an output cable from the rear post to the battery and you are done. (Also see our store listing for our 150, 200, and 300 amp 1-Wire versions) We build these units to provide 140 amps at an idle. That's as much as the original units put out at high RPM.
Our high output alternator can also be used to upgrade most original externally and internally regulated alternators from 1963 through 1987 year models. This unit is great for applications requiring additional charging capacity such as auxiliary batteries, stereo systems, off-road lighting, etc.
We also have this same unit as a plug-in for use with a factory harness in our eCRATER store.
Not sure if these units will fit your vehicle? Please email your questions concerning applications to us and we will respond quickly.
Please specify your choice of 1 or 2 V-Belt or Serpentine belt pulleys.
