Having read a few post's on here regarding charging issue's and stator, reg/rec failure's I bought and fitted a usb socket with built in voltage indicator and was a bit alarmed to see it indicating 15.7v charging,
occasionally peaking at 16v while riding.
Should I be concerned?

I must admit that I don't know but noticed there is a discussion on the theme here.. New Voltage Regulator.

Have you checked the reading is correct? If it's a cheap Chinese device, it could give any approximate reading. I bought a thermometer with three remote devices. The device is "Made in China" and all fore measuring units (three remotes + the base) gives different readings standing next to each other. Check with a quality multimeter or three different cheap multimeters. If the averige is still "high", you have a problem.

Like those folks said your too hot. Unless you’ve a lithium batter, they require a higher voltage but even then your borderline. Time for regulator change, switch to a non shunting unit.
sh 847 or sh 775 Same skill level as installing the meter, Google is your friend.

Great your off to dealer, hopefully you’ve caught the overcharging before damage to stator and/or bat ray. Don’t feel alone. I installed a meter during the 500 mile service. 15+ volts at idle…..so it’s going to dealer for a regulator as well as the water pump which I found to be leaking…..bother.
