[QUOTE="SWFL, post: 6535381, member: 607847"] well just got done playing around with it. playing juice box which is the most steady bass line and is constant so works good for voltage test. The front battery is around 13.2-13.35 at full tilt at idle. The back batteries are at 12.35-12.45. So roughly .75-.90 volt difference. I tested the voltage before and after the fuse holder on the two front holders that go to the back and same voltage on either side. I measured the back fuse holders that go to the batteries and its the same on the input and outout so the fuse holders i dont believe are taking any power if so its slight maybe but i dont see it. Then at the back batteries its 12.25-12.5 roughly and at the amp with short runs and fuses between the amp and batteries the amp sees 12-12.25 so loosing a 1/4 of a volt in that small run. Only thing i can think of is the fuse holders possibly or i need another few runs of 1/0 front to back and i am going to do direct grounds to the frame off the batts in the back as well. All connections seem fine. The two runs of 1/0 to the front are connected to the copper busbar that is connected to the front battery where the two runs of 1/0 from the alt are connected to. [/QUOTE]
