hi i think the rectifier has gone on my 3he
have read the write up about yzf rectifier
have got one of an fz600 is it possible to use this as it two extra wires
thanks in advance dai

Sorry but most of us have probably never seen the FZ6 Voltage regulator

what I can tell you is that 3 wires come from the alternator
1 wire is positive to battery
1 wire is negative to a chassis/ engine ground
on the FZR6 3he model

the rectifier has 1 black wire 1 red 3 white same as yzf
but also 1 brown and 1 green (thin wires) maybe for a volt guage dont know

You can disregard those. I believe the green will be for an accessory load...the brown may be a RF noise suppression ground or some such.

Either way, everything you NEED is there-as George said. Three AC input leads, one black to chassis ground, and the red DC voltage output to charge the battery.

In other words. It WILL work.

thanks will try later

yep it does work
stupid question what are the three white wires for

The stator is an alternator....as such, it produces Alternating Current (AC). Straight (unrectified) AC cannot be used to charge batteries(batteries are strictly Direct Current {DC} devices).

They use alternators on modern engines because they don't require any battery power to produce power. The magnets in the flywheel are permanent magnets.... and their field passing by the stator coils is enough to produce (inductive) AC. (DC generators need to have power to make power).

The stator is what is known as a three phase alternator (has to be-a single phase alternator would have to be muuuch larger to make enough power).

Each phase "leg" has it's own wire.

Those are the three white wires.

The voltage regulator/rectifier (commonly "VR") does TWO things. It rectifies(changes from AC to DC) the AC output from the stator/alternator...and then it regulates that DC to a preset level (14.5vDC or so) so that the battery(and other chassis electrics) doesn't get cooked.
