I have been smelling smoke the last couple of days but never could see anything.
Well last night i smelled it and popped the hood to a small fire burning - I keep a fire extinguisher in the trunk (EVERYONE SHOULD) and put it out.

The only thing i could see was the front two cylinder's FI harnesses were melted together. I seperated them and wrapped them with electrical tape and drove on home. Drove the car into work this morning and bought a BIGGER extinguisher - so far everything is normal.

Plan on getting some high temperature heavy duty sheaths to slide over the harnesses.

Has anyone had this problem ? What else should I look for ? Its a 1990 740 Turbo with 192,000 miles.

I had a coworkers whos 1987 760 burned to a crisp in GA 400

I've owned 4 normally non-turbos - never had a fire before! Time got a 960, S90...might as well get a SAAB 9000 Aero ( I like the looks) with this type of risk :)

    If everything is working normal, it looks like the only damage is at the spot you seperated. Take off your tape and make sure all wires are covered and not fused together. Re tape them and stop at you local auto parts, you can pick up the plastic harness cover like most new cars use, this will protect them from scuffing and shorting out in the future. Also check the routing of your wires so they don't burn on something hot or scuff on something under the hood. It looks like you lucked out and got away easy. It should give you no more problems if you follow those steps.
    Good luck in the future on your brick.
