Re: Battery Drain??? Voltage Regulator to blame?
full battery charge is 12.65 with the enigne off.
your multimeter has an AMPS setting right? use the 10 amps setting.
disconnect your positive cable, install a short jumper wire form your batty terminal to the cable. turn your key on, then back off. then hook up your mulitmeter PARRALLEL to your jumper wire, turn the meter on, then disconnect the jumper wire, thus putting your meter in series with the system.
this will show you rate of draw, should be under 50 milliamps. if it is high, start disconnecting fuses and accesories untill your amp reading drops. when it drops, you found your draw.
