CB500/550 / Regulator Rectifier Replacement
« on: August 19, 2019, 08:49:55 AM »
Am looking to replace the original units(s) with modern kit.
I am sure this question has been asked many times so apologies for any repeat !!
I seem to remember someone posting about a unit that just plugged straight in to the existing connector
I found this on a USA site but cant find an equivalent in UK

There are lots on fleabay and seem to vary a lot in price but this seems OK

ALso Wemoto have a what seems to be same unit but much pricier

I am assuming with these units connection as follows
In the existing 5 way connector:_The yellow wires connect to the existing 3 field coil yellow wires and the green (earth) and red (battery feed) to exisiing green and red
The remaining white and black leads are then the field coil connections that go where the existing regulator plugs in. I assume the green existing earth wire from the existing regulator is simply not needed
