I was under the dash yesterday, examining my fuse block..Apparently the PO had an issue on fuse #4, because of signs of arcing and the fuse being gone. Looking at the wire coming from the fuse position and the wiring diagram, leaves me a bit puzzled. The wire is a very heavy white wire with a red tracer. The wiring diagram only shows a white wire, running to the right headlight. Is this like every one else's ? Or am I in the wrong spot on the diagram? Thanks for your input...

You mean fuse number 4 on the additional fuse board. This fuse and the white/red cable is for the rear window heater. It is in Part IV of the original circuit diagram. My fuse also melted one time - it was more a slow decay of the fuse due to excessive heat at the fuse itself. I replaced it with a real ceramic one (not plastic) and cleanded the fuse terminals and it was never an issue again.

Thanks, Rubico...that stands to reason since the wiring at the hinge joint is kinda messed up back there. One more thing to fix..More fun!

Tiger I don't know about your hatch defrost, but on my car (originally from NH until I got it in 2013) the electrical "jumpers" between the hatch and the gas struts were corroded badly... the copper wiring on the extremities of the wires were green from oxidation, and in general the circuit was visually in poor shape.

I've replaced the rear gas struts and now the hatch stays open. My hatch to defroster wires were badly corroded also. However, now the attach point for the grid came loose and I have to go with a rather expensive solution of an electrically conductive epoxy. I'm scared about cracking the rear hatch glass if I try for a re-solder of the joint. The wires at the hinge point look a bit "weathered". Not sure if this is where the problem is, but along with the rest of the car, will be fixed. Year #4 coming up this summer, and still never driven. Sigh.

If you need any wiring harnesses, I have the complete wiring harness from an 84.

You mean you've had your car for four years and have yet to drive it?

Tiger03447

That's right, Tempest. It was rescued from a guy's back yard where it's previous PO (I guess I'm about #3or 4) had let it sit for about 4 years. All total it's been sitting about 10 years in the New Hampshire elements. Hopefully the fresh engine will be going back into it this spring or early summer. The TT has to go in first, however, which is almost finished. To be perfectly honest, I've only driven a Porsche once, and it was a 356, many years ago. Then it was only an around-the-block excursion. Nice but not as exhilirating as a TR3 or XK140 at the time. So, for now, I'll keep plugging along, fixing this and that, and installing new(er) or better parts as needed. As expected, this all requires many mini-projects that will ultimately reward me (I hope) into a nice daily driver that I can give to my son when I'm too old to drive it any longer. Thanks, sorry for the ramble.

Thanks, Fillily...I'll keep that in mind..the car's wiring is in pretty good shape so far. Soon, I'll put a battery into it and give it further electrical checks.

That's even worse than my Ducati story. Back in 2009 I bought a 1995 900SS and ended after a bit of tinkering tearing the engine down and rebuilding it. It was two years since buying it before I could actually ride it anywhere. Plenty of vehicles, once I've torn them down and rebuilt them I trust them to take me anywhere reliably, but the Ducati...I consider it a small victory every time it runs without the floats sticking and flooding the crankcase with fuel, or the charging system catching on fire, or some crack developing in the frame and/or swingarm...Old Ducatis are shady like that. As for a Porsche, I do not actually own one (or have driven or ridden in one, or even seen a 944 up close) but am just collecting parts for one. When I have an entire rebuilt powertrain to install I'll go looking for a 'roller' to put it all into.

I have an '89 roller that I will let go of cheapppp... comes with many spare parts...'89, partially stripped. come and get it..

tempest411

Thank you for the offer! I am intent on getting an early model though..I've already got a full suspension for it, an NOS early AFM, and Bosch-rebuilt DME for one

Tiger03447

The roller is pretty gutted..the guys who stripped it left half of a 2.7 L block(I think), the TT and the clutch. The wiring was hacked up, and the dash was removed..Still has the gearshift, 2 good rear gas struts, and a pair of early seats? mostly frames..out of my '83. Tail lights, and headlights, parking lights, all gone. Still have the front valence though..Fenders are good..(I'm keeping the Left front and the hood, along with the nose panel, which on my '83 were crunched..Still has the suspension under it along with the power steering..Could be rebuilt into anything you might want.

How is C-pillar trim on the '89, Rich? I have a friend with a 951 looking for some in good shape... preferably black.

Also, I have a 1983 harness if you end up needing one, although it's better off as a core for rebuild. I'm happy to measure/photograph any areas of it for reference for your project.
