Regulator Plug Retainers

1 products

Our range of regulator plug retainers for Harley-Davidson covers small clip and bracket components used to secure the voltage regulator plug to the regulator on vintage and Evolution-era Big Twin platforms. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks regulator plug retainers from MCS — the long-trusted Harley-Davidson aftermarket supplier of small electrical and hardware components. Fitment covers 1970–1988 Big Twin and 1989–1999 Big Twin (excluding Twin Cam), suiting Shovelhead, Evolution and earlier Big Twin platforms where the regulator plug retainer is a known wear point. The retainer keeps the regulator plug seated through years of vibration and weather — when it perishes or breaks, the plug works loose and intermittent charging faults follow. A fresh retainer during routine electrical service is cheap insurance. Browse the full range below.
