It is a neat kit to adapt a small car alternator to a twin. A departed Club member, Bert Weisz, had his own version. He had the smallest 12V battery he could find to excite the windings at startup. The alternator made so much power that he didn't need anything bigger. His job as night shift maintenance machinist at the Windsor, ON Ford works let him make a lot of Vincent goodies. Timetraveller is part of the team that makes the Walkernator.
