Where is the voltage regulator located on a 1999 dodge ram 5.9 cummins diesel?
On a 1999 Dodge Ram 5.9 Cummins, the voltage regulator isn't a separate, easily accessible component like in some vehicles. Instead, it's integrated into the alternator itself. You won't find a standalone voltage regulator to replace. If you're having voltage issues, you'll likely need to replace the entire alternator.
