I have a 2005 Ram 1500 SLT 2WD. When my ignition is in the "OFF" position, the only thing that I have found to work are the brake lights. Everthing else that should be working with the key off (the keyless entry, interior lights, headlights, etc.) all act like the battery is dead. When the key is turned to any other position everything but the radio works and the doors will not lock. I do have an aftermarket stereo with two amplifiers installed so I thought that could be a place to start troubleshooting but during my search on the internet I discovered some others that have had this same issue. However, I haven't been able to find where anyone has posted finding the solution to this issue. I have an electrical schematic for my truck but I wanted to see if anyone that could give me any information before I start ripping into the wiring. Thanks!
