I need help. I have a 2011 g37s sedan and it has a parasitic draw over 10amps. Also codes for camshaft and crankshaft sensor circuit came up after jump starting it. disconnected the alternator, unplugged camshaft and crankshaft sensors and pulled fuses but so far I haven’t been able to get anything to drop the amperage being pulled from the battery. Something is pulling over 10a, enough to drain the battery within less than an hour. Anyone had this problem before? tia

 

Gonna say no, not exactly a common problem or there would be a hundred threads about it. Hope you can figure that out before your car lights on fire. 10A @12V is 1200watts of power - like a toaster - so be careful! Start with the Fusable Link fuses - the big ones right off the + connector of the battery. Those are the main fuses for different "branches" of the electrical system. If you can stop the drain from there you will know which branch to look at.

 

If the fusble links dont lead you anywhere, might be worth disconecting the alternator and see if it clears up the current draw.
