Hi
Just wanted to thank you for your superb DIY on replacing the voltage regulator. I found a link to it in the Porsche Club GB forum.
I had very similar symptoms to those described in your post, so I took the plunge and decided to use your DIY and put a new regulator on. Battery now charging perfectly for the small cost of 24 GBP instead of a new alternator and a big garage bill!
Your DIY is excellent, easy to follow with very useful photo's and tips.
Many thanks indeed.
