Need HELP! 2012 WR450 weak spark

I have a 2012 WR450, 1000k on it, mint condition. Was working perfectly, installed an aftermarket gas tank and hasn't run since. 

 

Extremely weak zap from the coil - won't fire the plug at all and will barely make a spark holding the coil wire near the frame. I get a mile shock when holding the lead, so there is a bit of power, not enough to fire the plug.

 

Does anyone know of any safety system that I may have bumped while changing the tank to cause this? I'm 1000 miles from the nearest bike shop and would cost $3000 to put my bike on a plane and fly it there.

 

I realize the issue occurring during the tank swap could be a coincidence, but it's the obvious place to start.

 

Thanks
