I'm having problems with my 2003 Hummer H2 draining my battery so I did a parasitic draw and as I was doing it the voltmeter was jumping from 2.54 to 2.80 up to 3.00 and the relay for my air suspension is clicking and moving as I try to do the parasitic draw also my cluster gauge is jumping as I do the parasitic draw which I believe is due to the relay for the air suspension can somebody please give me some suggestions how to fix this problem thank you
