Hello, new to the forums, only had the Pico scope a month.
I have a Volvo which is reading a charging voltage of 15.6v, the battery test on the picoscope says the battery is ok but needs charging.
On closer inspection of the battery the cells are bone dry, and there is clear evidence of foaming and over spill from the caps.
Id like to know whether the voltage regulator is located on the alternator as part of the unit or controlled buy a computer somewhere else.
also is the high charge rate normal for a modern car like this,(2012 Volvo V40 D2) the condition of the battery say to me that it isn't.
so the alternator could be at fault charging at such a high rate or if this is normal the battery is incorrect for this vehicle.
Any ideas would be appreciated.
