you will have to replace the alternator because the voltage regulator is inside the alternator. If you know anything about mechanics you can tear the alternator apart and replace the regulator pretty easily for around $10.00.

Check the wires and replace regulator if old. Most times overcharging issues on older vehicles are due to bad wiring. Could be poor grounds at the regulator, frayed engine cmpt wiring, or loose wires between regulator and alternator. The external regulated alternators are dumb, they do whatever the remote regulator tells them to. If the regulator has an issue, the alternator just plays along and pumps out the current.
The internal regulated alternators have the regulator built into the alternator. These have a 2 prong plastic "DA" plug that plugs into the back of the alternator, and a third screw lug that charges the battery thru the wiring harness. If the DA plug is wired wrong it could cause an issue.
Auto parts store should be able to test either type, and tell you what should have been stock. It would help to get the manual for your truck, lots of good wiring schematics, etc.

Yes replace the alternator. The regulator is internal. Should solve your prob for about 40 bucks. Good luck

Have it tested first. If the meter is showing the same thing as your meter then its either the regulator or the alternator but if the meter shows 14 votls then your meter is shot.

get a direct voltage reading from the battery with a DVOM (vehicle running) if the results match your voltmete readings--replace alternator. if not----replace your guage.
