Puzzling Starting Problem
Every time I try to start my Bonnie it acts like the battery is dead--no crank at all. The voltage gauge reads almost at the bottom. However, all electrical components seem to function normally--all gauges work, I can hear the fuel pump, the headlights come on at full brightness, etc. The car can be jumpstarted easily and runs perfectly, but then will not start again without another jump.
Battery and alternator have been tested and are fine.
The most obvious suspect is battery cable corrosion, but I'm wondering if that would cause the voltage gauge to read so low while most of the electrical system functions so well.
Any thoughts/advice would be greatly appreciated.
