All other electrics in the car are fine. >Any ideas anybody? > Yes, surprisingly enough, a possibility. I had a 1980 Rabbit diesel that developed much the same problems. (Also continually broke the alternator bracket) Yes, it makes sense... Turns out that the engine electrical ground was established through the engine mount. That mount was bad.... Thus, the ground would break, cutting off the engine, and letting the power go through all sorts of odd paths. Not enough to run the car, but enough to make the lights light up oddly. The motor mount had always been bad, so the engine had always vibrated more than not. That explains the alternator bracket failure. IF Saab does anything similar, then check the grounding from the engine block to the chassis, or the internal grounding in the dash... No guarantees, but it does sound like an intermittent ground... Could also be the reverse, and intermittent power connection.. I'd check the fuses for the control/cabin stuff.... just pulling them out and visually inspecting them might get rid of the possible corrosion on the fuse blades... Harvey >Pete >
