I recently purchased replacement rear air shocks for my 2005 Suburban along with a Dorman Air Shock Compressor. Prior to replacing the shocks I had replaced the compressor a year ago. A month ago my battery died- I found I had a parasitic drain that I traced to the 30 Amp RTD fuse controlling the system- it was drawing 3 AMPS when I did AMP test- when I pulled the fuse it dropped to near o amps. When I removed the fuse the battery did not drain, so I thought maybe the compressor was bad again- wiring etc.
I received a new compressor under warranty and ordered Arnott shocks AS 2715. I installed them fired her up and it worked as it should. Next morning battery is dead again- checked the fuse and it was still drawing over 3 Amps.
So what else in this system could be causing the parasitic drain? Like I stated once I remove the 30 AMP fuse for this system the battery does not die, so somewhere on this circuit I am getting a draw and I don't know what else is on this circuit other than the compressor?. What other electronic components are on this circuit that might cause the battery drain?
