I have an 07 V6, the light started flickering and the next day the car died while driving. Lost all power and then engine stopped. Tried jump starting but would only run for a few seconds and disconnecting. Electrical system would then go haywire. Check the belt and it seems tight and fine. Normally I would have it towed to repair shop but here's the real kicker. I live in the Caribbean and we were just hit with a major hurricane. All shops are down. My guess is I need to replace the alternator, battery is brand new. Anyone have any suggestions? Thanks for any and all help!!
