Data logger showing the point where the light comes on: Any thoughts on what would cause this? Is it just a slipping alternator belt? There's no audible slippage but I guess it's quite hard to tell with the VHPD at full chat!
Am hoping the alternator isn't goosed as this one's only done a few hundred miles and not really been abused much yet. I'd have thought a failing regulator would over- rather than under-charge at higher rpm?
Any advice appreciated
