Question about 2003 Ford F350 Super Duty DRW SuperCab
All of you accessories can't run from the battery. The alternator has to produce 13-14 volts to you battery to keep the battery charged fully so all the accessories will work. Soon as a power source is powered on it will drain the battery quickly if the alternator isn't putting out. I would change the alternator. Honestly, If you have a shop close by that rebuilds alternators, this is the way I would go. Here in my home town, a rebuilt is $95 as a rebuilt from auto zone is $140-170 and comes with the same warranty. I use a rebuild shop for all alternators and starters. Cheaper and have never had to take one back compared to auto stores.
