Porsche 944 Kid

I will jump start my car and let it charge... Remove the cables, turn off my car and restart it... Turn off my car again and it will not start.
It will only start one time after being charged.

Sounds like something might be draining the battery. Happened with my motorcycle once, turned out the brights were on so it would start with a jump then not start again. Anything stuck in the "on" position that isn't supposed to be?

battery might be completely or nearly dead and unable to hold the charge. Time for a new battery.

plumbum

agreed...sounds like the battery is done

william_b_noble

what tests have you performed on the battery? what is battery voltage when disconnected from the car after charging. What is battery voltage 12 hours after charging (but disconnected from car)

The dead battery seems plausible, mine drains the battery when off, which I suspect might be a faulty DME relay. (Which, I -if I'm lucky- will get a brand new one in the mail today!)
