[QUOTE="piggy, post: 611505, member: 13218"] Thanks Matt, I went down a bit of a rabbit hole on You Tube looking at some Moss videos which were useless for the VW but found some other ones and did the test above that you mention. I also worked through the following link http://www.vw-resource.com/generator.html#maximum - Running the generator as a motor (briefly) by disconnecting from the car and then running +ve and -ve to a battery, connecting the field terminal to -ve on the generator made it run faster. Reconnected it and we are now generating 12V at idle. High revs and it blipped to 80V although I suspect this might be the voltmeter. Reconnected to the regulator and it is running at 12.5-13V at idle then up to 14V at high rpm. So in summary I think the only damage I have done is reverse the field polarity on the generator. Thanks for all the help James [/QUOTE]
