Bit of a odd one ... just had the battery changed on Mr Grey and before changing my volt meter( built into the sound processor ) it would show a solid 14.4 volts dropping to 13volts at tick over all good .
Changed Battery and display and hand held volt meter shows 12.4v constant even on tick over and when driving accelerating still shows 12.4v but on over run ( of throttle) it charges at 14.4v then back to 12.4v when I stop
Any ideas ??

Batteries usually hover around 12.4 according to the professional mechanics tester I nick off my youngest now & again if the battery was going south it will let you know its not feeling well 🙂

But why would it only show charging at 14.4v when slowing down ?

The Alternator actually chargers better at low speed according to a certain source (mechanical son) who services Police vehicles for a living & who shall remain nameless because he is bigger than me & I'm 6'3 but slight more rounded 😄

It seems strange that it was showing a good 14.4v charge on the old battery ( although not holding charge ) now it holds at 12.4v
Gonna get the guys who fitted. It to check that the earth terminal on the battery is tight as I don’t remember seeing the guy tighten it plus it’s not accessible without taking the plastic box surrounding the battery off
Thanks for input tho much appreciated
