Hey Scotty I have been watching your videos on repairs for awhile now but I have a question, recently I got a Ford F-250 with a 7.5l 460 Big Block but it has trouble with the battery draining to fast, when I use the windows or any kind of battery usage I can see all my running lights and my interior lights go very dim, Do I have to buy a bigger Alternator or just replace it? I just got a new battery so I know thats not a problem, thanks for helping me out if you can! -Colin Seaberg.

have it load tested, auto zones do that free. Often just a new normal one works fine
