My 2004 PT Cruiser just flashed the internal battery light. I was able to drive home, but I noticed that the LED lights on the clock were flickering. I played with the RPM of the motor a bit(manual transmission) and did not see a change. It Seemed to bounce with the roughness of the road.
I have a lot of miles on this car, and it would not suprise me if it was the alternator. I just got a new battery this summer. However, it is acting like a loose connection. How could I tell? I don't want to spend the bucks if I can just tighten a connection somewhere and solve it.
