Current flow charts- for C students

[OldSpool87]

I thought I read somewhere that there are wiring or current flow charts for the non-engineer type. A dumbed down version of you will.

Are there any recommendations out there for current flow charts that would assist the electrically challenged folk? I would use these specifically as a basis to start troubleshooting, for example, nonfunctional reverse lights.

Thank you

Mods- could you please move this to 911 Tech forum.

Thanks!

Bump.

Thanks

What year car?

You could try to look at one of the old style electrical diagrams and get an idea of the layout of the wires, etc.

In order to make sense of the new style diagrams you need the diagram, a key to what the symbols mean, and the location of all the components and connectors.

Thanks Trackrash. Car is a 1982. Is final reading you correctly the old style diagram serves to “decode” certain items which the “new style” omits. Where can I find the new style. Anyone have a general picture to share so I know what I am looking for?

Thanks

Ebay.

A guy makes laminated easy to read big font electrical diagrams for your SC. I bought them and they are great. Way easier to read than the back of the haynes manual.

The old style is more like a map that shows how the wires are situated with the components laid out in a similar fashion to how they are in the car. They tend to leave out some of the electrical details however. On the newer cars the electrical systems have become so complicated the new current style makes more sense.

When you get a diagram make sure you get the Description pages and you will need the "Electrical Component Locations" From the workshop manual as well.

Pelican used to have these diagrams available. A Google search may find a copy out there.

Saw these on a tech's bench at the Carparc open house during LA Lit week.

Well that wallows in lameness.

Is there a material difference in wiring between 1980-1981 and 1982?

I have that diagram. It is color and laminated. Unfortunately, there are a few mistakes.

The wiring diagrams in the back of the Bentley are easy to read. But there are a couple of mistakes there too.

Some diagrams omit European wiring options. For instance, the front heated windscreen option is a common omission.

But for the majority of uses, either are good enough. I tend to cross-reference the Ebay diagram, the Bentley and the factory diagrams.

I found a bunch of factory wiring diagrams here including the SC's: Classic Kabelboom Company - Bedrading schema's Porsche wiring diagram electrical elektrisch

The Bentley is pretty good for C-student simplicity, the factory diagrams take a little more effort to understand. Good luck!
