[QUOTE="theRealCrazy, post: 430383, member: 18115"] Yesterday morning car barely started , checked the voltage and it was under 10.0v oO... engine starting goes back up to 13.7v... I thought, because I changed the HU that I might have a faulty ground somewhere, so I decided to remove and unplug the whole HU... I charged the battery again and this morning back to 9.7V... I then decided to unplug the battery fully. I started charging it.. up to 12v, then using my voltmeter on both terminal I literally can see the voltage drop.... almost. 0.1v/2sec... oO I plugged a Pulse repair that I had laying around... but wanted to get your opinions..
