Connect to Yamaha’s 2nd battery charging option. This feature allows the house battery to be charged completely independent to the starting battery without the use of Voltage sensitive relays (VSR’s). This means that your accessories can run down your 2nd battery without affecting your ability to restart the engine. (MAR-6CEIS-0L-ED comes standard with 100 amp breaker switch protection) (MAR-69JIS-0L-ED comes with 50 amp blade fuse, replacement p/n 5140). Note that connectors on the engine are different for V6 four stroke models.
