What are some of the dodge ram 1500 alternator problems?

The alternator in Your Dodge Ram 1500 does not have any common faults that show up more often than others. Alternators in general do have a few common issues that can happen to any brand of vehicle. The most common fault actually isnt the alternator itself, its the battery. When the battery is old or damaged, it wont accept a charge even from a perfectly working charging system. The only thing You can really check on the alternator itself is the output voltage, You can do this with a multimeter. Set the multimeter to DC voltage and connect the leads to the positive and negative battery terminals. You should see a reading between 12v and 14v. Anything less or more than that and You have a faulty part that needs to be replaced.
