Need some help here understanding the battery charging side of the ignition system in the above mentioned motor. Here's what I do understand... The system has a rectifier (OMC P/N 583408) that charges the battery, unregulated, continuously, while the motor is running. Sometimes, even with a 6 amp system, the charge can be excessive to the point of harming the system & battery. A need for this system to have a voltage regulator has been established. There is a "kit" available from BRP to remedy this problem. It is a regulator (OMC P/N 173640). Now, what I don't understand... Does this regulator replace the rectifier, or is it used in addition to the rectifier? Are there other single rectifier/regulator combined units ( Merc, Yamaha, OMC) that can be used as well? Sorry for the TOME. Any advice offered will be appreciated.
