I've owned my '89 coupe since new and know it pretty well. I have an electrical problem and don't really know where to start looking. here's what's been happening:
A couple of weeks ago the starter began running sluggishly, but only on one turn, normally the engine turns over 3 - 4 times before it fires and one of the turns is sluggish, then it is normal. This problem stopped happening a week or so back.
This evening, driving home in the dark I noticed the instrument cluster lights were flickering when I was cruising on the highway at 2000 rpm, I also noticed the voltage varying rapidly from 13.8 to 14.9 volts, normally it shows about 14.0 on the highway and never goes above 14.6. With the ignition on and engine turned off the voltmeter shows 11.0 volts, normally it shows 12.2 volts in this configuration. I put a voltmeter across the battery terminals at home and it showed 12.5v.
I don't know if this is related but in the past week I've noticed a high pitched whine on the radio that varies with engine speed.
The battery was new about 6 months ago, the alternator was new a couple of years ago.
Could it be a loose connection somewhere, bad relay? I have no idea where to start.
Thanks,
Tony
