I think I asked this before but . . . I'll ask it again because I don't know what to do. :-/ I want to replace the resistor wire that goes from starter to coil. is it that simple? can I just diconnect one lead from the starter and one from the coil and replace it with a new resistor wire from porsche? if so. . . . the question I have is which wire is it at the starter that I need to disconnect and put my new resistor wire on? I hope someone knows because my other car is having problems now that I have to deal with and I'm going to be stuck with no working car pretty soon.

The wire connects to the starter post #16. It is a small black wire at the starter. This black wire connects (in line) to the 1.5 ohm resistor wire that goes to the coil post #15. The Haynes manual doesn't indicate the color of the resistor wire. The other resistor wire that connects to the coil #15 post is 1.0 ohm and goes to the ignition module. Unless the black wire is bad, you should only have to replace the measured resistor part of the wire going to the starter.

I can't ever figure much out from the diagram in the manual. what's the thing I circled in red? is that just a connection between 2 wires? where is that connection in the engine compartment? if someone knows where that is that would be helpful.

here's the part of the diagram. . . .


since I don't know which wire from the coil is the resistor wire that goes to the starter I guess I could disconnect the wire at the starter end and just tape that extra wire up. . . then put a new wire from there to my new resistor wire and add that to the wires connected at pin 15 on the coil. This is a pain. I hate 24 year old wiring.

The red circled part is a wire connector.

In this case its a 3 pole connector and the wire in question is fed from pole 1.

The other 2 poles are shown to the left and right of pole 1.

It is located in the engine compartment near the distributor.

Benino- you have the best (animated) little picture, under your name, that I have ever seen!

It's perfect.

thanks for the compliment on my animated gif. (made it myself )

I've added a green outline on the picture I posted above to show something else I'm ignorant about. What are the little numbers above the color indications on each of the lines?

I'm going to see if I can order a resistor wire from the dealer and see what I can do. if I can follow the wire thats there I might replace it otherwise I'll just disconnect it and add the new wire.

Those numbers are metric wire size (cross-section measured in square millimeters).
Conversion table to go from mm² to AWG sizes - http://www.rbeelectronics.com/wtable.htm
According to that table, 0.5 wire would be replaced with AWG-20, 1.5 with AWG-14, 4.0 with AWG-10

Here's a converter program that gives differing opinions on replacement sizes (0.5 = AWG-21, 1.5 = AWG-16, 4.0 = AWG-12) - http://www.mogami.com/e/cad/wire-gauge.html
