how do i find a parasitic drain on my battery in my kia sedona 2003
First fully recharge the battery, then hookup a battery cable, positive or negative either one, on the other battery cable put a test light in between the post and the cable end, if the light turns on bright then you have a draw that will kill a battery in a short period of time, so next electrically disconnect the alternator, if the light goes out or drops to a faint glow you have just found your draw, the alternator has a bad diode, if no change in the light start removing fuses one at a time noting where each fuse came from until the light goes out or drops to a faint glow, once that happens you need to find out what componets are on the circuit, locate the failed and repair or replace as needed, then start putting the fuses back one at a time and watch the light just to make sure something wasn't missed, reconnect the alternator, and battery cable. That should be it. Note the faint glow is called a parasitic load and is not an actual draw. If you would like to watch a video there is one on you tube about finding draws in your vehicle, they use a voltmeter but the results are the same.
