Collection: 10DN Series Alternators, Parts, and Kits

The 10DN series alternator was first manufactured by Delco Remy in the early 60s. It was introduced on GM's Chevy Impala roughly 1962. It was General Motor's first production run of an alternating current generator, or alternator. It was a replacement for DC generators found on older vehicles. These DC generators required a complex commutator and brush system which was prone to failure. The alternator, on the other hand, requires a simple two-pole slip ring and only two brushes. This design improvement lead the design for every other alternator design since, from Ford's 1G series alternator to early Nippondenso externally regulated units.

Unfortunately, the vehicles early alternators were designed for didn't have the electrical accessories available today. This means older style alternators are not designed to put out the kind of power you expect from a modern alternator. The 10DN used an especially thin and weakly wound stator. Stock output ratings are between 35-60A, a far cry from the 200A monster AD244 we sell today . Of course, these modern alternators don't have that stock look and feel desired by car historians and restoration enthusiasts. Until now, the only way to get more power is by overwinding thin 10DN stator cores, gaining amperage at high RPMs but losing it at low RPM idle speeds. With our exclusive and innovative upgrade can put more power in your old unit.
