1985 ATC250R has no spark?

I have a 1985 Honda ATC250R 3-wheeler with no spark and I can not figure out what the problem is, what are all the possible options I have to fix it? It has been sitting for quite some time, And the Stator behind the flywheel has 2 wire coming out of it and those 2 wires get power when the motor is kicked over, and there is a little black box next to the flywheel that when the motor is kicked over does not get power. We tested the wires with a light tester. Please Help I just want to ride it.
