Yamaha 40 rectifier installation

[MichaelD]

Hi,
I am seeking your assistance for the installation of a rectifier regulator for my 2003 Yamaha 40 3cyl. outboard (40VMHDL - Australian delivered). I have purchased Yamaha rectifier part: 6H2-81960-10. I am unsure as to which wires connect to where. My rectifier has 4 wires (1 red, 1 black and 2 green), and my outboard has 2 green wires coming from the underneath the flywheel. Any hints? Do I need a fuse? If so, how many amps?

Your help is greatly appreciated.

Michael

Connect green to green, Black grounds to engine block, and Red connects to positive terminal of battery, fuse is not needed, but you can put inline fuse on red wire.
