National Luna Dual Battery install problem.

[adio3x]

Greetings.

Just finished up the national luna dual battery install, solenoid flashes green, monitor is reading 12.6 volts (all yellow lights in the center are lit), no alarms, but my car won't start. Electronics work, lights work, but the car won't crank. I've tried taking the negative terminal off and on a few times. Nothing. At this point I removed the kit, car started up after 2 attempts at cranking.

Thoughts? Thanks in advanced!

I think I figured out the issue. Either the screw holding down the negative terminal wasn't super tight or there was a loose connection at the intelligent solenoid. Going to recrimp all the wires and see if that does it.
