Hi guys,it seems that my 77 is losing voltage from somewhere,after a couple of days sitting the battery will hardly turn the car over,the battery tests out good at 93%
Suggestions? cheers Dave

first check all connections , tight and clean , fully charge batt , remove neg cable and connect a test light between cable and post light should be on then one by one start pulling fuses if light stays on replace fuse and pull the next one if light goes out that is your drain. finding out why my be tougher but at least you will know which circuit to look at , hope this helps

check for any interior lights that may be on, they will draw the battery down, while you don't notice them on.(maybe a map light or a light in the storage box area behind the seats)

Some curcits are not wired thru the fuse box. If you pull all the fuses and the light is still on it could be a cucits not tied to the fuse box. It would be wise to get a wire diagram for your car if you are having electrial problems.
