Volvo Cummins isx won't start. Fixed.

My Volvo Cummins isx wouldn't start. Turned out to be dirty battery terminals. Vecu (vehicle electronic control unit) not motor ecu, wouldn't permit my truck to start because it detected a weak connection. Crazy part, they weren't even that dirty. Apparently it was dirty enough for the vecu. I attempted to start it after each new part or cleaning. Batteries were bought 6 months ago. Starter 2 months ago. Ignition 7 months ago. I hope this helps. Older models will let you start, with slow cranks, heated wires or terminals. Newer models won't let anything happen.
