Title: RECTIFIER REPLACEMENT
Post by: triplE675 on July 08, 2015, 07:16:47 PM

My 500KO is not charging suspect its the rectifier ,

Can a rectifier / regulator with zenor diode be used with 5 wires 3 for the generator phases + battery feed and earth wire

If so what happens to the voltage regulator circuit do ii need to remove or disable ?

Thanks

Andrew

It doesn't use a zener diode it uses a solid state voltage regulator but yes you can use one. This regulator adjusts the current in the field coil and therefore regulates the output of the three phase stator to match the battery charge condition. The later  Honda bikes use an integrated rectifier and regulator, the regulator parts being a solid-state equivalent of the electromechanical separate OEM item.  Regulator-rectifiers are cheap on eBay, just check its been tested  if its a used one.

Don't want to hijack, but in that same vein, is one reg - rec unit better than another, or are the cheap ones just as good?
