automotive electrics are much more maddening than the commercial building wiring that I'm used to. However if i were able to pull all the old out and start fresh like I do at work it would be much easier to understand what wires are doing what. I plan to do just that in the future probably with a non-Porsche fuse panel and new wiring.

Be sure to use Thinwall cable. It is multi-stranded copper cable which is insulated with thinner hard grade PVC which offers good resistance to abrasion and cut throughs. The cable also carries a higher load compared to the standard automotive cable (because it dissipates heat easier), so you may be able to downgrade the SWG (AWG or CSA) in some circuits making the car lighter and thus more economical. It gives savings in volume/bulk as well as weight when used in large harnesses too.
This cable is now original equipment on most new vehicles but would not have been fitted 20 years ago.

The cable you are using at work will probably have an insulation resistance to withstand voltages of up to 600v~ if you work with 3phase mains installations. Thinwall has a low voltage insulation so its no good for domestic or industrial mains, but high voltage insulated cable isn't needed on a car

the_mad_electrician it didnt sound like I pushed it in yer face did it.
Ive been at the maddeningstages with the wirin and i spliced and replaced some stuff. Trying to keep all the stock switches went away a long time ago on the Na project though the 931 still has a chance.

I think if you make a new starter/ alt loom to see if you can get away from the smokin
sizzlen wire thing that would be good. Once you go there its time
for open wire surgery.

As long as nothing grounding out any where the heavy ground by the coil shoudnt get hot like it is.

My girlfriend is having electrical work done on her 1979 Porsche 924 dash.
Apparently the wiring diagrams in the Haynes manual are inaccurate and our friend had to order the 924 factory manual to get accurate wiring diagrams.
