I was looking at one of Fords websites and it shows :
For a 1998 E-350 , 6.8L V10 , there are ( 95 and 130 amp alternators listed )
It normally means the alternator is not putting out enough voltage to keep the battery charged and is defective. Can be a loose alternator belt also.
On a 1994 E350 motor home with a gas 460 engine, the voltage regulator is typically located on the engine's alternator or mounted on the firewall. It's often a small rectangular component attached to the alternator itself or nearby, depending on the specific setup. Checking the vehicle's manual or wiring diagram can provide exact details for its location in your particular configuration.
in the tank
It is in the fuse panel under the driver's side dash; fuse number 9, 30 amp.
on the firewall next to the battery
Try changing the battery.
Go to the Ford Motor Co site and you can download a complete owners hand book.

The voltage regulator is built into the back of the alternator. It can be changed if you are able purchase one through a automotive electrical rebuilding shop. Most places just want to sell you a complete alternator. www.autozone.com Click component location.
