Ford F-450 2010 6.4 diesel. Fully loaded 170000 miles
Ok I'm a dumb shit and thought that when you battery light comes on that meant you needed to change out your batteries. I didn't know it was for your alternator. The dummy light had been on for 3 days. I did charge both batteries at night. But come the 3rd day the truck engine turned off and everything went dead. Thinking I had dead batteries, I charged them but now I have no power at all. It's like I blew fuses or something bad. Need help to identify problem. Could the alternator found itself out somehow. Couldn't charge batteries while the positive cable was hooked up as it would trip the charger. Any thoughts pretty please. Thanks
