Answer 1
You may have some sort of battery draw that needs to be isolated and illuminated. You would need an amp meter disconnect one cable of the battery put your Amp meter in series with the battery cable that has been removed. Note the draw say for example 15 Amps, with the keys out of the ignition, doors closed driver's window down, start removing the fuse links and fuses one at a time until the voltage draw goes away to zero (or near zero about .02 to .05 Amps is about normal for a modern vehicle with a clock, stereo and other things that need "keep alive memory"). It is that circuit that is causing the electrical draw, then look at a wiring diagram, see what consumers are on that circuit and start to isolate each circuit to see which is the culprit. Modern cars have lots of computers and electronics that need constant battery even with the key off so parasitic draw of .2 Amps may be normal sometimes things stay "live for a minute or two after the door is closed so wait and look at the draw after a minute or two. You would need to put an amp meter on the battery cable note the battery draw then remove fuses one at a time until you see the draw go away. One the fuse that has the electrical loads on it that are causing the draw is found then the consumers on that circuit need to to be isolated one at a time to see which one of them is causing the problem. To get a wiring diagram There is a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect....
