Regulator Harness

3 products

Our range of regulator harness components for Harley-Davidson covers replacement wiring harnesses and connectors for the voltage regulator circuit on Big Twin and Touring platforms. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks regulator harnesses from Cycle Electric and Namz — two American specialists known across the Harley-Davidson scene for charging system and wiring components. Fitment includes 2004–2005 FLT/Touring (Twin Cam) and universal-fit options that cover most Harley-Davidson Sportster, Softail and Dyna applications where a custom or replacement harness is needed. Damaged regulator wiring is a common cause of intermittent charging faults, often misdiagnosed as a failed regulator itself — running fresh, correctly-pinned harness components ensures the regulator's full output reaches the battery. Whether you're chasing a charging fault or wiring a custom build, the right harness keeps the system reliable. Browse the full range below.
