1990 964 Vexing Electrical Problem

Electrical and Electronic

Vehicle Information: Model: 964; Year: 1990; Body Type: Coupe; Total Mileage: 87000;

The engine will suddenly cut under acceleration (mild or strong acceleration) and a/c blowers will turn on and off while this occurring (not mere slow down of blowers due to loss of alternator current but complete cut off). Also, engine will suddenly shut down while idling. This accompanied by the clicking of all the relays in the fuse box. Engine compartment light remains illuminated even with engine cover closed and ignition off. Auxillary electric engine cooing fan runs continuously irrespective of temperature. Of course, all this is intermittent to boot, although less and less so.
