Universal 12 Volt Regulator for Kawasaki Snowmobiles

Interceptor, Intruder and Invader - 1978 to 1982 - RMSTATOR RM03801

A brand new universal 12 volt regulator supplied as a direct replacement for the original unit fitted to Kawasaki Interceptor, Intruder and Invader snowmobiles built between 1978 and 1982. It is a plug-and-play, direct fit part with no assembly required, so it goes straight onto the machine in place of the original without modification to the loom.

The unit is built with a higher grade of electric components than the original, and the manufacturer states that the quality exceeds the OEM equipment. It handles a maximum charging current of 20 amps or 150 watts, holds a minimum charging voltage of 12 volts plus or minus half a volt, and is rated to operate anywhere between minus 20 and plus 85 degrees Celsius - which matters on a machine that is started cold and then works hard. Every unit is tested before it is shipped.

Frequently Asked Questions

Does this regulator need any modification to fit?

No. It is a plug-and-play, direct fit replacement for the original unit and requires no assembly. It mounts in place of the original and connects through the single four pin plug on the 155 mm leads.

What is supplied?

The regulator unit itself, ready to fit, with its four pin plug already terminated. Every unit is tested before it is shipped.

How do I tell whether the old regulator has failed?

The two classic symptoms are opposite ends of the same fault. Either the battery is never fully charged and goes flat, or the system over-charges and boils the battery and blows bulbs. Measure the voltage at the battery with the engine running: a healthy system on this regulator holds at least 12 volts plus or minus half a volt and the open circuit voltage stays below 15 volts.

What charging output will it handle?

The unit is rated for a maximum charging current of 20 amps, equivalent to 150 watts, which covers the standard charging output of these Kawasaki snowmobiles.
