i would check the fuse, it should be in a round red fuse holder and normally will say fuse, but its hard to miss as its red and has a large cylindrical tapered tube where there is an inline glass fuse. pull the two ends away from each other, pull the fuse out and check it, and if the connections are dirty or corroded, clean it off and try it again.
if still nothing, get a test light and see where you have power, try at the battery clamps, then the main power wire that goes to the starter solenoid, and the smaller wires that are on the solenoid. the smaller wires feed power to the rest of the motor from there. also check to make sure your neutral safety switch or emergency kill switch is working properly.
most likely you have a bad connection or a blown fuse. if you dont have a test light, invest in one, they save a lot of trouble trying to figure out where your missing power.
