About This Product
MCS wire-type plug retainer for regulator/rectifier. It fits 1970 to 1999 Big Twin models excluding Twin Cam. It installs on the outside of the crankcase. It prevents the regulator/rectifier plug from vibrating loose or disconnecting from the alternator stator plug. Electrical issues on these models often stem from poor connections at this point. It replaces OEM number 517772. Sold as a pack of five.
Manufacturer part number: 517772.
Fitment
