    Ignition switch problem 67S

    Hi friends,
    It has been a hectic summer, but regrettably not on the road.. :-(

    When I turn the key, nothing happens except that the tank, oil and pressure needles jump.

    The problem started last season and gradually got worse. In the beginning it happened from time to time, but it was just to try again and it would always start. This spring it took maybe five attempts before it would crank, then 10, then 20 and now it is completely dead.

    Today we loosened the switch to take a look at the back. Its dirty and should be cleaned. The red/white wire was loose, so we connected it again, but nothing changed. I should have studied the wiring diagram and done more research, but starting to get desperate. Im more or less retarded when it comes to electricity, so please go easy on me.

    Any input to narrow down the problem would be greatly appreciated. Is it the switch or could the problem be somewhere else??

    Thanks, Radmund

    First, get a test light (electric screwdriver), looks like an ice pick with a 12v bulb inside.
    Look up a wiring diagram (I'll help try and find) and bypass the switch, i.e jumpstart. If it cranks good, the switch is bad.
    If not, move downstream..

    Time flies, but we have now discovered that I have a bad connection in the fuse box. With a helper putting pressure to the fuse, it cranks like normal.

    How would you proceed from here? For me it seems very logical to switch to the CDD Autogear alternative that looks great: https://www.cddautogear.com

    Yes, I know some will argue this will make the Porsche gods annoyed, but I really do not care too much about that or having to live with the original panel on a shelf. I need a car that is as solid as possible. Electrical problems will never be my strength and I have a very small network around here to help me out when I run into problems like this.

    Please chime in if you have an opinion or if there are alternatives to CDD that needs to be considered.

    Thanks!

    Your choice,,,,it seems an ohm meter will tell you what the problem is with your fuse block, might be an easy fix, if not go ahead and try to change everything over to a new system. What could possibly go wrong? Take LOTS of pictures before disconnecting anything. If you do have a problem I'm sure the vendor will help.

    Determine the fault in the original fuse box before committing to a very major project. 50+ year old wiring does not suffer disturbance gladly and you might well be launching into a project that an electrical novice will never complete.

    Dennis Powell on Pelican (Timmy2) is the go-to guy for harnesses and electrical needs. (I like the blade fuse panels.)

    "Crimp on" connectors are the bane of auto electrics. I despise them.

    Here's a proper end at the fuse panel. '77 Carrera 3.0.
