Hello, I have a 2006 F 250 Superduty (5.4L V8). I removed the factory head unit (AM/FM only) and put in a Pyle Aftermarket CD Player. I used an aftermarket harness soldered to the harness that came with the new Head Unit. All connections seemed like they are soldered well.
After I connected the aftermarket head unit, it turned on well and worked fine. After listening to the CD player with the engine NOT running, I found that the battery was dead between 5-10 minutes. I recharged the battery and it held a charge just fine. I tested the system for parasitic draw with a DMM, and it registered a 10 mA draw with everything turned off and the CD player unplugged. So there obviously isn't a draw that is killing the battery.
This leads me to believe that it is the new head unit and a short somewhere. However, the CD player works just fine (until the battery dies).
Any ideas?
