Q: new battery is draining within 24 hrs, everything checks out ok by mechanic who is still testing more parts

asked by on March 25, 2016

Last week went to start car & it was dead, no sounds at all. Roadside service tech jumped battery so as to move it out of my garage & onto tow truck & towed to mechanic who said 3 yr old battery was the problem, so he sold me a new one. I picked up car & went out for several hours, then home, car was fine. Next day. again car is completely dead & was retowed back to mechanic. He checked out alternator, starter, ignition, fuses and then checked "Light Control Module" & tested a new one overnight, but next day he called to say that was not the problem either, so he is continuing to check what else. Can you please give me some hints of where else to look for problems as the mechanic has my car for several days now & I need it back asap. Thank you so very much for your help..
