Yeah, the fuse panel on this car......you sent shivers down my spine. I have a 1980 928s. I bought it in 1986, way before the internet. Back then, if you didn't know how to speak German, good luck! People had to order a $350 translation guide just for the fuse box. And that's 1980s $350 dollars. Everything labled on this car is in German. You have to love these cars to really keep them on the road. I have 10s of thousands in mine, and it's probably worth 12k-15k. These cars are very expensive to maintain. If you can not work on your own car, this is not the car for you. Most mechanic shops will not touch it, neither will body shops or paint shops. O'Reillys, AutoZone, Napa, none of them will have a single part in stock for this car. Everything has to be ordered and get used to waiting. But to be fair, when all cylinders are running, not much on the road that can keep up. But when this sucker breaks...........
Not all are in this good shape. As we can see, it must have spent many days in a garage. The switches are not used. But that is not the problem. It is the age of the electric if it is NOT used enough. It will always turn on and start immediately, but all the little electric helpers get old.
