Reassembly
Step 1: Reinstall the completed 4-cell back in the battery tray. Orient it like the picture below. Route all the wires through the slot in the side as shown.







Step 2: Place your box on the chassis with the open side facing the back of the car. The battery has 2 holes where plastic pins from the chassis should fit inside.

Step 3: Reorient all the wires so that the circuit board is on the top cover, the servo motor is hanging off to the left, the switch/charging jack is hanging off to the right. In terms of colored wires, the red and black wires should be on the right and the green and brown wires should be on the left. Left and right are as if one is sitting in the car. The potentiometer should STILL be hanging off the front of the chassis plate and the rear pod off the back.

All the parts of the car really have to go back together at once. The following steps will try and break it down one by one.

Please note, during reassembly KEEP the parts orientated as described above as best you can.

Step 4: Connect the potentiometer to the servo gear set. The leads of the potentiometer should be on the right as if you were driving the car. If you are having trouble with orientation, look at the cut out for the leads in the top of the chassis.

The arrow in the picture is pointing to the hole where the pinion gear from the servo motor will go.
