Where or when was it determined that the alternators in the pictures were 17si's? They look like CS144 cases to me from what I can see, not the best angles or pictures. Just curious not trying to start anything, just want to know what the differences between the two are.
Ok a cs144 is what you would call a cross from a 17 si and a 21si the housens are 17si but modded to house a 21si stator. The rotor is modded @ the com end to house a 7-101 wide bering the same one in the ford 3g in sted of a neddle bering. The regulator is a cs130 and rectifier is a 21si with 6 70 amp diods and if done right will produse 300 amps cold not hot. If a good match between rotor and stator you might see 250 hot. Idle @ rotor rpm can be set up the same way you set it up on the test bench As the same rpm you will be seeing on the car /truck/van If you have the right tools and pully`s. it will all work out in the end
