Hi there,

You will need to do current draw test, do this by placing an Amp meter between the battery Pos terminal & the battery lead, with the key off & doors closed, check the currant draw, if over around.2Amp start pulling fuses & fusible links to locate the problem circuit, also don't discount a faulty Alternator as a blown diode in the regulator will cause this as well but the alt will still charge albeit at a slightly reduced rate.
