Been having some battery drain issues resulting in a beeping low power sound when getting in to car
checking with pa soft its giving a Vehicle power < 9 Volt and then after a while it will flatten battery eventually.
Live results in PA soft showed a 11v rating
Ive fully charged it up externally and now im getting 11.7v the following at position 1
with engine running and nothing on this goes to 13.6v
with 2100 rpm its showing 13.8v
and 2500 rpm with full aircon, lights and wipers its at 13.4v
i gathered its meant to be approx 14.2-14.8v with engine running if all working well
given there is an increase from engine off to engine on, im "guessing" the altenator is working so would this be a battery issue not taking a higher voltage and not retaining it :?
or am i barking up the wrong tree
all help appreciated
