I have a 2005 Suburban with all the bells and whistle’s Z71 have a parasitic power drain. pulled all fuses and relays one at a time but did not get the voltmeter to move more than 4mA, currently pulling about 82 to 88 Milla amps. All doors and accessories are closed and off.

Any help would be great, Thank you.

 

Disconnect the alternator and check the parasitic drain.

 

thought that might be it and tried it with no luck. Still pulling over 80mA
