I built this alternator in 1985 and adapted it to my 1950 Ford tractor when I converted the tractor from 6 to 12 volts. It just failed recently. Originally, 29 years ago, I seem to recall having a problem with the rotation as far as charging is concerned. Whatever problem I had, if any, was fixed b/c it has been charging since then. Looking at the drive pulley, it rotates clockwise. Is this an issue I will have to deal with? Or will it charge in both directions?
