I recently swapped a 77 ironhead motor from a swing arm frame into a hardtailed frame. I had to relocate the old Bosch style regulator from the rear of the bike to a mount that sits ontop of the 65a generator and also upgrade to a smaller battery (AGM YTZ-12S from lowbrow). The bike fired right up and charged fine for a couple of miles but then stopped charging all of a sudden. I removed the cover off the regulator to find one of the contact points, the first big one, welded shut. I broke them apart, sanded them down and rode for another couple of miles until it happened again. I’m confused as to why it is happening, and wonder if someone can explain to me why they keep welding shut. I’m aware that heat causes this so please save the obvious. I would like to run this setup instead of dropping the cash on a cycle electric voltage regulator bolt on thing if possible.
Should there be more wire length between the regulator and generator to help slow down the charge (don’t think that’s how it works, but…)? Is the heat transfer from the case to the generator and then to the regulator causing it? I’ve seen this setup on other bikes, so I’m skeptical. Anyway, please share your thoughts. Thanks
