I fitted this earlier, I’m very good at running out of charge with my phone when out on rides, it’ll also power the sat nav, so just been for a ride, running at approx 6k revs it’s 14.2v and doesn’t go above that so reg/rec is doing its job nicely, but I got a surprise when I switched the lights on, it read 14.4 and up to 14.6 but didn’t go above that, I know nothing about electronics, does switching the lights on employ another phase of the alternator or something?, Cheers Mark
