About 2 hours into a roadtrip, all the lights (brake light, parking light, etc.) came on and we figured the alternator was about to go out. Drove about 20 more miles and the radio died and sure enough so did the car like we expected.
The next day when we came back to retrieve the vehicle via tow, the car started up just fine (even though the day before it was so dead we couldn't even turn on the hazard lights). Not wanting to risk it we had it towed back.
The car is running but I'm afraid to drive it anywhere. I had the alternator and battery both tested at two different shops and they are working perfectly. Checked the cables and connections for corrosion but everything's fine.
However, all the lights are still on that came on prior to the car dying. The car is too old to hook up to diagnostic.
