[Chevelle-list] BATTERY DRAIN

[Jww1945]

I have a '70 LS5 and am having battery problems.   I will drive the car on weekends and put it under cover Sunday night and then the next Saturday morning the battery is dead.  This past week I started it up on Wednesday without a problem.  Went out this Saturday afternoon and their was not enough battery strength to turn the engine.  Clock was still running and the dome light was very weak.    Over the past month I have installed a new battery, alternator and voltage regular.  Put new correct cables on it two years ago.   Any thoughts what is causing this battery drain?   Thanks, Jerry Wells ACES 5923
