Battery drains power even when car is off, bought new battery, problem still
Someone will need to check all of the circuits to find the power drain.
Could be a stuck relay, short to ground, or faulty switch among other things.

The fact that your battery is drained makes me think you may have a short somewhere (where could be anyone's guess) This would put a constant drain on the battery. Have you checked your Voltage regulator or fuse? It's possible if the voltage regulator went bad that it could have blown a fuse causing your vehicle to shut off. -I had a lead wire come loose from the battery in a Van I owned. -while driving. The whole car went dead. -On the side of the road scratching my head looking at the engine. Ended up noticing some frayed wire... Got my wire strippers, trimmed it, re-attached and POOF! On my way again like new in 15 minutes. Have you installed any accessories recently that could have accidentally caused this?

you need a volt meter. unhook the positive side of the battery. set the meter to dc amps. touch one leed to the battery and the other to the positive cable making a circuit.if theres more than 1 amp or so being pulled,that will drain it in time. sart pulling fuses one by one untill the draw goes away.then you will know what circuit it is on. after that ,start chasin wires to find the short.

have you checked your battery post for corrosion build up?
give them a good cleaning, then give your wire leads that connect to the battery a good cleaning as well, wire brush, sandpaper, whatever you got to make them super clean so they can conduct that 12 volt current.
you might also want to follow those wires/cables/leads (whatever u wanna call them) ..and clean the other ends..or make sure they are not corroded..the ground wire especially.
clean them up real good..it costs you nothing, and may solve your problem.
hope this helps
let me know

The battery current draw may be caused by a few things, here are some to check: the most common is that a light stays on like the dome light, the brake l;ights may be staying on,aftermarket accessories can cause it as well, audio amplifiers or stereo equipment or aftermarket alarm systems, very common.
