I found a way to get a worn out Renix crank position sensor working. Wire a 0.01 uF capacitor across the sensor's wires.
uF stands for "microfarads".
0.01 microfarads can also be expressed as 10 nanofarads (nF), or 10,000 picofarads (pF).
Don't use an ordinary ceramic capacitor, heat affects them too much. The ceramic caps are the little orangey-looking discs.
This worked like a charm for me. The cherokee wouldn't start at all, no spark no matter how much I cranked it. I wired the capacitor up and it started right up. I'm an electronics hobbyist so I had bags of capacitors of different values. I tried 0.1 uF first; the jeep started but didn't run right. A 0.01 uF poly capacitor worked like a charm.
So guys, if you have an old jeep take along a .01 uF capacitor when you go trailing.
