Got a 02' tracker that keeps on discharging battery. Got new bat. and still disharges. How u check for parisitic battery drain?

 

Take the negative post/cable off. Sratch/rub it against the post...you should NOT see a spark. If you see a spark, you have a short/drain. You can also hook a mulit-meter up, or use a test light (what I like to use). Start pulling fuses until you have no juice flowing. When you pull a fuse and the test light goes dark...SHAZAAM, you have narrowed it down to the circuit that has the short.

That is about all that I know about it.
