Just when I thought I killed off the gremlins.....
Once the bike heats up to when the fan kicks on, the idle charge drops from a 13.9-14.1 V down to as low as 12.8 V. Have R/R from roadstercycle (less than year old), hardwired to a Ricks stator (less than 2 years old), and a few month old Shorai Lithium-Iron battery. Just replaced all coolant hoses about a month ago... wondering if this could be a cause? I've done "The Drill" so many times, I now do it in my dreams. Everything checks out fine, stator putting out proper ACV, continuity/grounding tests come out good. R/R is doing its job, I have never seen it hit 15 V, battery is rock solid. I've checked the infamous orange grounding block, didn't look fried up at all. I'm thinking there must be a shortage or grounding issue on the bike, or maybe something with the electrics involved in the cooling system. I also noticed a burnt out tail light bulb and a headlight bulb that will flicker on and off a few seconds upon starting the bike. Anyone else experience this?
