NIPPON DENSO INTERNAL VOLTAGE REGULATOR (YAMAHA)

It's time to upgrade your alternator!

The Nippon Denso motorcycle alternator is an excellent unit, used on many makes & models of motorcycles. It is compact and powerful, and usually requires no maintenance. The only downfall of the original units is the voltage regulator unit. The original regulators often fail allowing overcharging, or no charging at all. When they allow overcharging, they fail by permanently energizing the field coil, a quick way to destroy an expensive piece of your alternator.

We come to the rescue with an advanced voltage regulator for the Nippon Denso alternator. We use a modern single Integrated Circuit (IC) chip to accurately control your alternator field coil. This results in a higher charging voltage, longer lasting battery, and more reliable unit. Our unit offers precise voltage regulation, short circuit protection, reverse battery protection, and has a thermal safety shutdown to protect the alternator. Our easy 2-wire installation makes this upgrade a must for your motorcycle!

Brand new voltage regulator

• RM31000 is a regulator that replaces the internal regulator 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.
• Even though RM31000 looks different compared to the stock regulator, it fits perfectly
• All products shipped are tested

There are several advantages of choosing our regulator :

• MUCH better heat sinking 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 RM31000 voltage regulator is better to the stock one and will most likely outlast the alternator it is installed in!

Warning:

Battery condition is extremely important. No voltage regulator can work correctly with a bad or weak battery. Always fully charge your battery before performing any charging system tests or replacing parts. If there is any doubt, have the battery load tested or replaced.
