Ok for those insterested I just did a current draw test on my 05 Avalanche with the following setup
Autopage 855LCD w/shock sensor
GM-U7 data buss interface
1x Battery back up siren
Autopage in valet 35ma
Autopage transmitting 65+ma (meter responese slow)
GM-U7 data interface 5ma
GM-U7 in programing mode 15ma
Battery backup siren 32ma
Battery backup siren turn "off" 23ma
Autopage, battery back, GM-U7 71mA
2005 Avalanche w/Onstar and BOSE stereo
"ACC" w/radio on 4amps (4000mA)
"ACC" w/radio off 3.7amps(37000mA)
RAP w/radio on 4amps
RAP w/radio off 3.7amps
Door open w/dome lights off 3.1amps
IGN on 14amps
Appears the onstar turns the radio on when door opened or something. Automatic 4amps +/- draw.
Unless I missed something (all alarm fuses pulled) the truck pulls 50ma without an alarm.
