whats the max it should be? 14.4v is an ideal i have heard and since my battery went kaboooom i put a multimeter across the new one.
from cold its hitting 14.8v and then coming back to 14.5 to 14.6v and not increasing under throttle which is fine.
but is this overcharging? only other time i have heard a battery pop from overcharging the alt was throwing out 18+v
new battery isnt getting hot either and nowts changed for months (ie no new dodgy wiring )
on another note, the environmental health and the council both refuse to move the old (wide open) battery as its not their problem
