Model 65A Generator

The Model 65A generator was used on Sportsters and Big Twins, starting about mid-way through the 1965 model year. The Model 65 generator, introduced at the beginning of 1965, had brush sticking problems, and the 65A solved this by rotating the brush plate 180 degrees to put the positive (insulated) brush on the topside to keep it dry. This required swapping the position of the A and F terminals. The Model 65A can be distinguished by the A terminal on the left, looking from the commutator end. A chrome-plated outer cover was optional on the XLH.
