I have recently acquired a 1992 C4 Corvette in a real estate purchase. It had a completely dead battery when I bought it and I didn't know if it it would even start (had been sitting for over a year). I checked all the fliuds, installed a new battery and after just a few cycles it started right up. It ran rough (old gas I assume) but no other issues. I let it sit for about a week and when I came back to start it again...nothing, dead battery. Charged it...started right up. This time I disconnected the + battery terminal when I left it. Went back, connected the battery..key clicked twice with nothing, then on third try started right up. Drove it a bit (10 minutes or so), while driving the lights flickered once and the engine sputtered, but then was fine. Came back, turned it off for about 5 minutes. Went to start it again...nothing, except the interior lights go on/off and there is a clicking noise behind the glovebox. Haven't tried re-charging the battery again, but thought I would see if anyone has had the same issue. Any ideas????

 

Time for a new battery?
