Check the voltage at the battery, Voltage at the generator really means very little, as it does not take into account any voltage drop in the wiring. At the battery posts, 14.2 is ideal, while up to 15V is a little hot, but will be OK.
If you do need to adjust the regulator, first make sure the ground wire from generator to regulator is clean and tight, as a poor ground will send a false low voltage signal to the regulator and cause high charging voltage.
The cover must be on the regulator when checking voltage after adjustment, as the magnetic field carried by the cover changes the regulsator setting a bit.
Another thought, what is the outside temp when you are reading this high voltage ? A battery needs higher voltage to charge at low temps, so the regulators are designed to compensate for low temp and increase charging voltage somewhat when it is cold. Once again, check the voltage at the battery posts, you may have no problem at all, as checking at the generator may well give a false high voltage reading. The voltage at the battery is what counts.

Today's Featured Article - Trenching With a Plow - by Staff. Introduction: This interesting information came from one of the discussion forums here at YT. We thought we should place it up front so it could be read by anyone interested in putting old iron to work. [Editor] I tried something new today, and it worked so well I thought I should post it - in case it might help someone else. I'm running 100 yards of 4" drain pipe from the gutter downspouts of our house to a pond down the hill. This should hel
