15.7 volts measured at which terminal of the isolator?
There are two leads going to the terminals of the alternator. One of them goes through alternator light and provides power to start the alternator anytime the key is on. The second terminal is a sense line to the alternator to tell it that the voltage in the coach is correct. I would get out a wiring diagram and start measuring to see if those wires are intact.
When mine went over voltage it was a poor connection on the sense lead where it plugged in to the alternator. I squeezed the terminal with a pair of pliers for a better connection and took care of the problem.
