2009 Saturn Vue hybrid battery drain
12 volt battery drains over night, when
started charging system at 14.4 bolts. This
is a hybrid is the alternator going bad or
could it be auxiliary control module, or
something else. This just started two days
if it charges at 14.4 V, the alternator is fine. If the battery drains overnight, it is probably old or you have a parasitic draw which is a circuit that is shorted and or drawing power from the battery when it is off. What is the voltage of the battery? How old is it?
battery is around 6 months old when it's charged and holding its around 12.3 - 12.5v in morning around 9.5v.
you have a parasitic draw then, check youtube on how to do it yourself if your good with a multimeter
Thanks for your help Jeff
