1. Only the sound box works but the raptor is not moving (even after fully charge the battery for 18 hours).
If battery is no good, you need to replace a battery. Click here for detail.
If the battery is good, you may have a bad pedal switch.
Remove the gas pedal switch holder, you can find either you have 3 wires (BIG YELLOW, BIG RED, and small yellow) or 4 wires (Two yellow, Two purple) connect to the gas pedal switch. Please disconnect those wires and try to reconnect them back in because there might be loose connection on the switch. After reconnecting wires to your gas pedal switch; turn the car on to see if this solves your problem. If not, you will try to do the gas pedal switch test.
