968s burning up?
Has anyone had ther 968 burn up yet? If what I found today is typical toasted 968s should start showing up soon!
Installing the starter my brother noticed some copper wire showing. Upon closer inspection we discovered that the main lead to the alternator and the trigger lead to the starter selonoid had both become brittle and the insulation was broken off. Bare copper was exposed in a couple of places and the 2 wires were separated by a paper thin piece of plastic. This was a disaster waiting to happen!
I noticed some exposed copper and brittle insulation at the alternator end when I installed the alternator a couple of days ago so I stripped back the harness and re-insulated that end, but today's discovery was that the entire length of the harness had gone brittle!
A word of warning gang, if you touch the starter or alternator wiring check to make sure it's not shot!

FWIW this appears to be common to all 944/951/968 variants. Check them and change them whenever possible and nec. Mine were atleast that bad, if not worse on the 951. You 'should" see strange changes in your voltage guage, and it's possible to have the starter lead ark to the bell housing under really hard acceleration. Don't ask how fun that is, especially with oncoming traffic.

I had one go up, but it was because a battery charger at my mechanics exploded and took down my car and 89 Countach anniversary edition, Maserati Ghibli and a Classic Pontiac convertible.... We didn't even get to drive it, 1993 Red Raspberry Metallic on black coupe with 20k miles, it was shipped in from CA to Fl, came of the truck into my mechanics and proceeded to become TOAST... not the means you are discussing, but thought I would share..

I would think it's less of a problem with the newer 928s and the 968. The injectors clip directly into the fuel rail, unlike my '84 928 where they have a short section of hose connecting them to the rail.
I had the 928 hooked up to my exhaust gas analyzer in the garage one day, the car running and the analyzer analyzing away. As I walked around the nose of the car to tweak a setting on the analyzer I noticed gas POURING from one of the injector hoses. I dashed around the car and shut it down quick as I could, then went back to examine the problem. One of the hoses had come loose from the top of the injector and gas had flowed all over that side of the motor including down over the exhaust manifold. A cup or so had puddled up in the valley and there was a cloud of vaporized gas rising from the exhaust manifold. That could have been a major disaster if I had missed it for even a few seconds more!
Anyways, as I said, I think the earlier 928s are much more succeptable to this type of problem than the later 928, 944 or the 968.
