Hi,
Just to recap, I bought Porsche positive pole covers but found that they conducted and were shorting against the chassis. I didn't think this was an issue with old ones so I have been trying to locate some used covers instead.

Upon speaking to Porsche about this, they informed me that another plastic cover is supposed to fit over the rubber pole cover. On the diagram below, part number 3 shows the rubber pole cover and part number 2 shows the plastic pole cover cover (!).

I am curious to know when these plastic covers (part 2) were introduced since I thought only the rubber pole covers (part 3) were used. Or maybe I'm wrong and they have always been needed and were always there?

Also, if anyone has a couple of old ones to spare that do not conduct, please let me know.

Kind regards
Gitesh
