If it still does not run after pressing the safety button then the next step I would take is to look for loose or disconnected connectors, or for any wires that may have been cut or broken during the move.
These motor wires may need to be checked by hand to make sure that the copper wires under the plastic insulation are not broken. This can be accomplished by bending the wires one at a time up and down the length of the wires and feeling how much bending resistance the individual wires create, then feeling if in one particular area the bending resistance is less than it is in the rest of the wires. If you are handy with electronics and own a multimeter it can also be used to check the resistance of these wires as they are being bent up and down the length of the wires.
Shana Hoercher replied through email: "That diagram that you sent there was no safety switch button anywhere located on the crazy kart the only switch or button that is located on the crazy car is the on off switch. When I press the gas pedal down I can hear the actuator kick on but it does not give any power from that point on. I'm not sure what to do now. Any ideas?"
You must have an early version of the Crazy Cart that does not have a safety switch button. Where on the cart is the sound of the actuator kicking on coming from?
