battery warning light flickering
hey all i have a 99 4.0 and i recently noticed the battery warning light flickering. The headlights also dim somewhat when this happens. No issues with starting the truck or hard starts. No other related issues. Don't drive the truck much and just noticed it because I had to drive it in the morning so it was dark. usually I only drive it during the day otherwise I wouldn't have even noticed it. any ideas?
