This part is aftermarket, but for the price it worked great. a week before leaving on a trip my regulator crashed and burned. Needing to get on fast and in time, it worked out perfectly. Part is made in Japan, but then again an OE part is made in Japan too, at a third a fraction of the price.
Far superior quality replacement for old iron with alternator conversion
I put a alternator conversion on my 1976 XLCH 1000 and the voltage regulator that comes with it burned up. After figuring out the OEM replacement part number I found these and they work very reliably as long as they are properly grounded (ground thru mounting it)
