Charging System - Yamaha F225F Service Manual

Charging system

This model features a high output charging system that provides up to 70 A.
This charging system also functions as a battery isolator that will charge a house (accessory) bat-
tery.
The engine ECM senses the voltage of the main battery and house (accessory) battery based on
the signals from the Rectifier Regulator.
If the main battery voltage decreases below 13.5 V when the house (accessory) battery is con-
nected, the regulator function of the Rectifier Regulator will be turned off by the engine ECM to
increase the efficiency of charging the main battery.
