Just bought 1990 Bronco w/351. Thought alt was bad so I replaced it. After replacing alt. I charged battery all night, came back this evening and battery was dead. Had battery load tested, and it tested good. What might be drawing the battery down in such a short time?

Hello

Many things can cause an electric draw. You will need to search your vehicle carefully to find it. Interior lights, glove compartment lights, etc.. will all drain a battery quickly and is sometimes hard to notice. More information about why your battery may be draining can be found at the link below..
