I have an 06 Santa Fe that is drawing around 5 amps when the key is out of the ignition and nothing is on. I had the battery and alt. checked and both are good. I took of negative bat. cable and ran a meter between the terminal and cable. I pulled all fuses in the engine compartment ant the interior fuse box one at a time, but the amps never dropped. What's my next move to figure out what is draining power?
