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.
There are two possible regulators for the Arctic Cat 400 Manual 2001 and Arctic Cat 500 Manual 2001. This regulator fits models VIN S91T306171 and up. For the models up to VIN S91T306170, the right part is RM30007. Always check in the 'Fits models' section and please compare to your original part before buying.
