So my battery gives up the ghost after two or three days. Fully charged it today, 14.04 v when running but with the engine off I put a 12v light bulb in between the negative cable and the battery and it glows brightly. Old school test but A good one. Any ideas where to begin?
Thanks
John

Although tedious you can pull fuses 1 at a time to see who is drawing all the power with the test light and positive terminal under the hood. Or if your a contortionist put the test light between the neg like you were doing and pull fuses 1 at a time til the test light dims. Would be much easier with help and faster too.
