I've been having trouble with my car's battery the past few weeks. The first time, I was driving home from a movie when all of a sudden, my interior lights cut out, as did my dash clock/radio and headlights. I had both the battery and alternator tested; both passed. After that, the battery would only stay charged for about a day or two at most. Yesterday, I finally had a chance to replace it. I put the brand new battery in, went home and charged it to 100%. This morning before I left for work, I tested the charge: 100%. On my way home from work, however, I felt/saw the familiar signs from the past few weeks: severe engine stumbling (especially while driving), dim lights, the engine sounding like it was slowing down. I made it home safe and hooked up the battery charger: less than 25%.
The only thing I can think of is either: A) my alternator isn't charging the battery or B) there is a faulty wire somewhere making the battery discharge.
NOTE: A few weeks ago, I had the spark plugs and wires changed. Is it possible that one of the plugs or wires is arcing?
have the same problem?
