Wet regulator
OK, here's the story. Coming home from work yesterday I got caught in a vicious rain storm. Rained so hard the roads flooded to the point my floor boards were under water. I pulled under some cover and waited for the rain to stop. Rode home. While riding tonight, I had my low beams/passing lights on along with crash bar mounted fog lights. I noticed when bike was at idle the voltage meter dropped to around 13v. When I activated the turn signals, the meter would fluctuate between 12v and 13v. Soon as I got above idle the meter would go back to normal. My bike has never done this before, she is an 08 EGC that I keep on a battery tender. I suspect this is possible related to my voltage regulator getting wet in yesterdays storm. Is that possible? How suseptible is the voltage regulator to moisture? what do these symptoms sound like to you guys? I have a lengthy road planned in august so need to get this squared away before then. thanx for the help. IF I turned off the fog lights and passing lights then the meter seemed ok and only had a slight twitch with the turn signal on.

The regulator isn't built to be submerged. You might have gotten moisture in the connector from the stator. Thanks to dielectric grease you aren't outright shorting out, but you might be bleeding off current all the same. The output of the stator rises with speed. You can load a bike down so much with electronics and lights that you don't have enough power off the stator at idle and have to draw off the battery. Presumably you know your bike and you normally run in the 14's at idle. I don't think there's reason to think the voltage regulator nor stator are in need of replacement, but the bike might well need to dry out. You could try to help it along the way by inspecting connectors and drying things off.
