Over voltage

So I was out riding trails and mudding in my 2016 Highlifter 850 for a good 4 days while camping. On the last day I was riding I noticed I got a message on my Screen saying over over-voltage 16.9. This is first time it has happened to me and at idle it wouldn't hold constant idle. Would rev back and forth. I have a planet audio water proof speaker box with Bluetooth so I can play music on trails. Well I noticed my audio box started to mess up either going quiet or shutting off but it was fixed whenever I would wiggle the plug inside the car charger plug near handlebars. But it would go out again next bump I hit. Shortly after that is when I first got the over volt error pop up. I immediately unhooked my speaker box so that's not an issue anymore.

What would be going wrong here and how would I fix it? Could the audio box shorted out and drained my battery rendering the battery useless now? Should I get a new battery or could it be what I've heard either the voltage regulator or my stator?

Please help me out and thanks.

u can only test a battery when its fully charged so id charge it and bring it to a battery shop to get load tested first. Than test voltage output from regulator, must be around 14 volts with your radio off !!!
that thing must put a constant drain on your charging system. Maybe check the stator wires for damage/rubbing.

My Ranger 900 done the same thing awhile back, it was the voltage regulator. You can pick a new one up on eBay fairly cheap.

Yeah, the ret/reg probably shorted a diode and is allowing AC voltage into the DC circuits - new unit will probably fix it

I'm not the best with electrical but I did test my rectifier and stator. Testing them both several times, they both passed and seem to be good. I don't know what is happening

If you you get over voltage it is your regulator you stator is putting out good charge otherwise you'd get low voltage and your regulator isn't regulating the charge goin to your battery. If it was low voltage there are other possible options but with over it has to be regulator.. Check out rm stator for new one they sell mofset brand I run 2 of them on my bikes seem at least as good as oem they claim much better.

Did you unplug the stator and test to ground { should read infinite from any of the yellow wires .

Test the rectifier by unplugging it from the wiring harness and use a multimeter to test it as detailed in the service manual
