Ok, I've got a Haltech E6K 1st off, Second. Relocated the battery to the passenger compartment. I have a NEW alternator on it. Scrapped off the paint where grounded. I ran 4 gauge wire and it still is discharging the battery. I'm stumped. Here are some pics if they help??

 

When you say discharging the battery do you mean the battery dies over time, ie: when the car sits over time or when the car runs you don't see more than the batterys 12v?
