Hola me again, been volt meter testing my squealing alternator earlier after dim lights (since fixed)... not sure on readings. I read a steady 14.28ish on idle at battery. With everything on, and I mean everything (Caravelle so that's all rear blowers/lights too), 12.1v'ish. Seems a bit low. Anyone reckon changing the belt is likely to be enough to give it the extra few v, it needs doing and squeals like mad, or am I dreaming and should I change it soon/get an updated alternator?
