1994 PORSCHE 968 User Comment / Complaint

All electrical power stops abruptly immediately killing the engine and all power to lights. you can't even put on emergency flashers since there is no electrical power. appears to happen when a higher electrical load is introduced such as a/c or high beams are used. most recently, this happened on a two lane highway where the only lights available were the vehicle headlights. when all power stopped at close to 60mph it was pitch black. without knowing the side of the road, i had no choice but to pull over missing a telephone pole at 50mph by inches. the resulting inspection shows the wiring harness close to the windshield under the passenger side windshield wiper shows that if you wiggle the wiring harness, all power is restored. the engine will start at this point and the vehicle can continue until the next power surge which then kills the engine and all lights once again. no fuses are affected by this.
