Hi All.
My VR has given up the ghost and I am wondering if anyone here is using a Solid State version.
My alternator is a SEV Marshal in a 76 911, I believe either 70 or 75 amp unit.
If anyone is using a a newer VR what is the part and where did you buy from.
Thanks in advance
Mike

Hi Mike,

on my '74 with the SEV Marshall alternator I fitted a HUCO 13 0427. At the time they were readily available on eBay etc - cost around £20.

Page 14 of my restoration thread for the Manhattan project.

Hope that's helpful
Andrew

Or just use a unit with an internal VR. We reproduce the Porsche Service
