Default melted eng wiring

Has anyone else had a prob with there wiring on there eng?? After I got my '94 SSEI last June every so often it just die and I could not figure out why. Here'* what I found: About 4" of the wires going to the cam sensor had melted togeter and it killed the comp. I had to replace that and I also rewired the 6or8?-wire harness that runs from the coils under the nose of the supercharger and to a connector by the alt. Again the wires where melting and the shielding was flaking off. I think there'* more cause I keep getting a intermint check eng/trac off lights. Comments/ ideas?

I've never heard of this.....sorry for jumping in a little late. Your traction light will be unrelated. You most likely have a wheel speed sensor going out. Are the wires routed in the factory location? I'd be really curious abou that since it'* happened twice now.

The only thing I can think of is that your nosedrive unit on the SC is running hot. If you took some temp measurements after driving around for 30 minutes or so, we could make some comparisons.

What kind of temps should I see? As for routing this is the only SSEI I've had and there rare around here so I have not been able to look about to tell if it was correct. I repaired both wire bundles at the same time cause the wires have the same kind of jacket they all would be prone to failing. It reminds me of Kapton coating that we no longer in planes because it caused too many shorts. I have routed the bundle over the top in the stock wire holder that on the charger. Would this wheel sense cause some kind of code to set? I have one of the OBD1 with the OBD 2 hook up cars. I love the worst of both worlds.

I need a little more info about the SSEi before I can give an opinion. Good luck with Rosco.
