voltage spike
My 13 RG has been flawless till a few weeks ago, have had low voltage 10-11v on start up, burp the throttle and goes to 14v, last week wouldn't get over 10v, tripped ck engine lt/battery light. I did a battery test, checked ohms on stator and volt reading, which after taking regulator off, cleaning the ground and reisntalling, worked fine till last night, started bike, 14v, rode for a mile fairly hard and when sitting at a red light v gauge dropped to 11v, throttle burp didn't help, then meter went to 16+, all lights went out as if a reset then returned to 14v+. very unstable, HELP

Yeah my gut tells me V regulator, battery recovers fine when loaded w/ everything on and not running. 1st time of v spike but other than the main fuse being loose, regulator will be my first replacement.

Yep, I'd also say it's the voltage regulator.
I have a '13 CVO Ultra and last summer at just under 27,000 miles while on a trip noticed that my volt meter was reading just a tad over 10 volts.
(While the bike's volt meter may not be total accurate, it will give you a head's up that something is wrong).
After checking the battery cables to make sure they were tight, I made a run for the nearest H-D dealership and they installed a new (non-CVO) voltage regulator under the ESP. (I didn't want to sit for two days waiting on a part just because of a little bit of chrome).
I suspect (but cannot prove) that my regulator could have been in the spate of bad ones from the '12 model year bikes.
