The reason so many batteries fail or melt down on the 600cc or 1000cc motorcycle engines is because the factory charging systems can put out too much or not enough voltage when charging the battery. Stock factory rectifiers vary greatly on the charging voltage output. The Hot Shot Rectifier uses MOSFET technology to achieve a constant charging voltage set point of 14V +/-.2.

MOSFETs (Metal Oxide Semiconductor Field Effect Transistor) are semiconductor switches which act to control the flow of electrical current. The design relies on a switching mechanism that provides a more precise control than other methods, particularly in low-power applications like motorcycles due to its quicker switching capabilities. This in turn produces less heat as less energy is lost through the switching process. The result is a part that runs cooler and more efficiently improving engine performance and a more reliable unit due to the cooler running condition creating less stress to the internal electronics.

In our 600cc Micro Sprint class, the engines are full throttle and a constant 12,000 to 16,500 rpms adding unplanned demand on the stock rectifier. The Hot Shot rectifier can handle the extra workload easily.

The stock motorcycle rectifier connectors are not sealed. During racing, dirt, grime, and water get in the connector and can short out the wires. We see this happen all the time. Symptoms can be anything from breaking up down the straight to melting down the battery.

-Will work on any of the major motorcycle engines

-Rectifier with 5 wires: 3 stator wires, and 2 wires that go directly to the battery

-Extra heavy duty sealed connector, crimped onto the rectifier (rated at 46 amp!)

-Battery wires with ring terminal included

-Connector for the engine side stator, uninstalled (User will need to crimp on)
