Well i have had my 1986 928s2 for two weeks now and today the 928 electrical gremlins decided to pay me a visit.
When the car was being driven some of the guages would fluctuate as though there was a bad earth, then they would settle down. The cd player would suddenly switch off, and when driving it home last night the voltmetre inside the car was showing just above 12v. This morning the battery is flat! Whilst having the timing belt changed last week the garage put a new battery in the car as it was flat when they tried to start the car. The alternator was checked and showing 13.5 volts so it was deemed as serviceable.
I have driven about 100 miles since the new battery was installed with the car starting first time.
Is it possible all these problems could be down to one thing?
I didn't find the right solution from the Internet.
