Information on the 1950-1951 Indian police generator from Roger Hensley:

The generator was  made by American Generator & Armature Co. and was not a special unit for Indian.  It was rated at 25 amps.  It has a cooling fan on the pulley end which requires a cut-back in the upper flange of the belt guard.  The commutator end was open, and Indian part # 333,013 was used as a cover. The battery was made by "C&D",  their part no.  UV-37.  It was rated at 45 amp-hours.  With this setup the regulator, Auto-Lite VRR-4001-B, was mounted on the chainguard.
