Hi ALl
Does anyone know where I can get a regulator for a 6 volt positive ground CAV dynamo,Or anyone that can repair them.A wiring diagram would also help.My local repair man [who is always very helpful]has never before seen one,he says the setup is different to anything in Canada.It is a gear driven dynamo so I have to have on the tractor.
Thanks in advance Tom

If you are able to find a working 6 volt regulator the polarity can be reversed to suit. My auto electrician did a 12 volt one for me.

The regulator that is located on top of the dynamo became obsolete in 1959/1960. They were replaced with a Lucas unit that was mounted anywhere convenient, usually on a plate fitted to the right hand side fuel tank mounting. These regulators are easily obtained in this country.
davidbrownparts.com have them and post worldwide.
If you PM me your email address I can send you a diagram.
