2002 Ford Focus Q&A
2002 Ford Focus Question: The battery light comes on and off while driving and it scares me.
First noticed the light to come on while driving to work. The light came on and then it went off. Took the car that after to get my battery tested. The guy at the auto store told me my battery was bad and put a new battery in. Thought that fixed the problem until I noticed that the light was still going on and off. Took the car to get the battery, starter, and charging system all tested and it all came back normal/good. The battery light however still comes on and off while driving. So what exactly could be causing the problem and if I don't get the issue fixed soon, could I damage my car's system? - Jazmine1025
if everyvthing checks out then check for loose connetion - goodguy
I agree with goodguy's advice to check for loose connections.I personally have replaced alot of focus alternators that were doing EXACTLY what yours is doing due to an internal failure. - bmdouble
