Battery Will Not Hold Charge

[rvw]

95 SC400 - Replaced alternator and battery. Battery will stay charged for 2 days and then will be totally dead. Charge it up and 2 days later - dead - ugh. Any ideas as to how to trouble shoot ? Thanks

i found out that my 12 disc cd player would drain my battery when the lid was shut. then again its broken and wont work all it does make sounds like its going through all the discs.

do you have any aftermarket alarms or anything?

door or trunk pins are not staying open causing it to turn on the lights, check the trunk.
