re: ground strap
<< (snip) I noticed that the '85 urQ has such a wire installed as well, as
did the newer GT Coupe. The ground wire is a moderate sized braid
that went from the right front of the valve cover to a spot on the
body right above the right headlamp. I've been meaning to do this
to my car as well.>>
My former '86 4000csq also had this ground strap, as well as one from where
the coil was mounted on the firewall to the cylinder head. Braided very fine
strand copper; they both stayed intact but corroded very badly and weren't
providing much of a ground. I replaced them both and had much better luck...
ground straps run a couple bucks each.
I'd also recommend cleaning the grounding points on the other straps, such as
the battery negative to body connection; they corrode over time and build
resistance. Cheap and easy fix. While on this subject, has anyone added an
auxiliary ground strap to the alternator from the battery? I remember that
New Dimentions (VW performance shop) used to sell a "massive overkill" harness
that worked wonders with charging problems on VWs, where the alternator ground
usually consisted of the mounting bracket...
