Mine is starting the flashing battery light again as it has twice in the past. Both times I replaced the alternator and it fixed it. Now I need another one, Advance Auto is going to get tired of me getting a free replacement all the time. When I pull my camper I use a invertor to run two small refrigerators while driving down the road. My alternator really gets a work out and that is the reason they keep wearing out. If I replace the alternator again and the light keeps flashing well then, I might have one of the problems listed above.
