won't start with battery moved installed an optima in the rear. I have a master kill switch and a fused distribution block up front near where the batterry used to be. The kill switch works, all my grounds check out, I have 12.59 volts at the distribution block but when I put in the fuse for the wire that runs over to the driver side post( at the fuse panels) my voltage drops to about 5 volts. My fuses are good the wire shows continuity but as soon as I give it power it drops voltage to the entire system. When I pulled the battery there where 3 wires on the positive post. 1 goes to the starter, 1 goes to the alternator and 1 goes to that post. The ground wire I cut and grounded it to the chassis. Any ideas?

ended up measuring resistance to ground at the back where I had the rear battery grounded and where the original battery cable was grounded and it was a huge dif. Tied a seperate ground between those two points and voila! You would think with welded sub-frames it wouldn't be that much of a difference. Lesson learned.
