Battery goes dead after sitting

Asked by Feb 03, 2014 at 03:11 PM about the 1960 Chevrolet Corvette Convertible Roadster

Question type: Maintenance & Repair

My older vette (60), after sitting for awhile, the battery goes dead and will not start.  I recently changed the voltage regulator and the problem persists.  The car does have a clock that runs but I have other cars that also have clocks and no problem starting after sitting for the same amount of time.  Any suggestions as to where the leakage might be occurring?  thank you all

Bad battery or radio.The best thing to do is disconnect the battery ground if it is going to sit for a while.

I'd say the battery is bad. But just to make sure get a 12 volt dc test light. Disconnect the positive battery cable. Wire your test light in series between the battery post and the disconnected battery cable. Remove the fuse for the clock and close the doors so the interior lights are off. The test light should not glow at all. If it does, something's pulling power. One by one remove and reinstall all the fuses until the test light goes out. Once it goes out, there's your problem circuit. HTH. -Jim

I have a 2014 corvette, we were on vacation for two months had trickle charger plugged i (I thought) came home and battery dead. I heard ai should not try and jump it, should I put in a new battery?

If the battery is less than about 3 years old, remove it from the car and charge it. If it's older, just replace it. By jump starting it with a completely dead battery the alternator will have to charge the battery. That puts an excessive load on the alternator and may burn it out. A new battery is cheaper!
