Re: battery drain while parked - why?

The infamous part that is the culprit prowels in many vehicles and that is
the Bosch alternater regulator. Sometimes when a lot of power consumers are
used the regulater doesn't have the ability to recover and so your battery
doesn't recover either.Battery may also be weak causing the regulator to
insult the injury. Check battery then replace regulater. Doing a test on
alt wont show anything
