i've been having trouble with my electrical system here latley.when im coming home at nights with the headlights,foglights, and sometimes wipers on, when i use the turn signals, the radio would flash and the headlights would dim. This only happens when the car is either cruising or idleing. when you give it gas and get up in the rpms its fine. so me and my dad are thinking that its a battery problem. we have had the alternator checked and its fine. but could there be a dead cell causing me to gradually loose power?
