Alternator conversion kit BT41-69 Chrome

Now you can convert your old generator equipped Harley to a reliable 12 Volt alternator system that gives 17 Amps. The alternator bolts on in place of the original generator. Kit includes alternator, regulator/rectifier, gear, oil deflector kit and mount screws. On 1941 thru 1957 Big Twins the generator screw holes must be enlarged to 5/16" to fit the supplied generator screws.
