Nippon Denso Internal Regulator

Part Number: ESR025
OEM Part Number(s): N/A

A voltage regulator that replaces the internal unit inside Nippon Denso alternators. This alternator is commonly used on certain Suzuki GSX-R models, on Yamaha FJ models, and Kawasaki Ninja models between 1984 up to now. This new unit looks different to the stock one, fits perfectly, has much better heatsinking capability and incorporates a thermal overload circuit. This circuit is important because it shuts down the regulator if the alternator rotor is shorted, a problem that is very common now. Typically the OEM voltage regulator dies when the rotor shorts out. Our ESR025 voltage regulator is superior and will outlast the alternator it is fitted in!
