Where should I start? I checked key switch and battery fuse and fnr switch. All looks good.
Since you were zip tying the cables, I suspect a plug got pulled a little. Make sure all plugs are fully seated.

If that doesn't do the trick, disconnect charger and computer, if they are connected, and break out the DVM.

To get an XCT48400-PDS to power up, you need battery pack voltage on J1 Pins 4, 5 and 8. (Unlike the stock PDS controller, you don't have to have a direction selected to power up an XCT)
