on my 2005 pontiac montana paracitic test is 0.33a is that too high

Asked by Apr 03, 2015 at 06:28 PM about the 2005 Pontiac Montana SV6

Question type: Maintenance & Repair

I know there is a lot of thing in the van, like OnStar, DVD, air compressor, ac converter etc.
Does that draw sound too high. I disconnected the one battery cable and waited for 1
hour before testing. I made sure the van was not touched in that hour. When I connected
the brand new ohm meter, auto troubleshooter 10 amp setting it reads 2.69 and then
slowly drops and stops at 0.33

Normal draw on battery from security and clock is 0.05 amps. See http://www.cargurus.com/Cars/Discussion-t9484_ds530227. The top answer in green for best answer is right sort of, Should be amps not volts The clock and radio draws 0.02 and anti-theft 0.03.You are 10x over the norm.

Example: a fully charged battery, mid quality@ 70°F can drain at that rate for 25 days and still start car.
