Ammeter shows steady center under load and at idle a minimal discharge. These readings are from an under dah mounted voltage gauge, reads steady power coming off of auxiliary port on fuse box. Mechanical regulator at idle battery voltage changing from 12.8 to 14.3 while idling (Warm) slow change not rapid, without taking the hood off and setting my DVOM directly to the battery to confirm where should I start looking or is this just an overly sensitive gauge? Is my Mechanical regulator set to high?
 
Yes but read the end of that post. He found a bad connection that was causing the high voltage. If all of the wiring is sound, then it could very well be the voltage regulator. Make sure you test and verify the regulator is grounded properly also. A digital ohm meter is your friend here.

I do have a fluke DVOM at home so I am all good there. I will go back over all my connections and make sure my grounds and resistances are within specifications. Thank you for the thread link
 
Hopefully you also have a wiring diagram. You need to take the time and patience to check and verify all of the charging circuits to make sure you don't have a bad connection. If you have a different regulator to try first it may save some time but if it is still sending too much voltage to the battery it is more than likely a bad connection somewhere.
Good Luck!

I have a FSM but was a bit lost, no extra regulator will check and adjust i adjusted a few weeks ago because it was only putting out 12.8v and did not have the battery voltage gauge installed at the time.
 
Made a few adjustments and i believe i got it dialed in yesterday 12.78 at idle 13.8v under load without headlights on with lights drops to 13v but no over charging, for now it is good for cruising may need a little more adjustment but good for now we will see how the rest of the season goes.
