Sabertooth 2x5 help needed

[dmess62]

I am doing a bruder delta loader conversion following along SmallHauls thread. I have a small pro boat 6cell 7.2v mini v battery. I am using a external bec to run the receiver for the servos. When I hook everything up to test motors they work. When I stuff everything in loader nothing. The light on the sabertooth shows no power. I took it out and if I move the drive and turn wires around by wher they are soldered to the board it cuts out. It almost looks like the touch each other when pushed down. Which is necessary to fit in the loader. Also when I have it out of loader and have power to sabertooth it starts getting real hot real fast. If anybody has any idea on what I may be doing wrong here any help is appreciated.
