Rick's Motorsport Hot Shot voltage regulators are high performance, heavy-duty versions made with special MOSFET technology that does not get hot. They run cooler and more efficiently and are protected by a separate inline 40 amp water-resistant fuse, further protecting the integrity of the system. Most of these regulators are an easy install, direct replacements, and come with the factory plug ends. If you have a unique machine, they will come with wire leads only and you will need to hard-wire it.
