The basic set-up is a quite simple 6 volt circuit. It might look complicated if you see all those bits and wires cramped together in the car, but we'll lead you through the installation step by step.
In the left colomn you will find a list with parts commonly used in a basic set-up.
The drawing shows where and how they should be connected.

You 'll see that they are nicely grouped together, the red wire is always the + (positive, the black wires are - (negative or ground).
If you follow the sequence indicated in the drawing, it will make no difference you where place the separate parts, on the chassis or in the body.

Step 1
We'll start on the left off the drawing, both wires come from the Motor.
The first step is a 1 amp 16v Diode in the + (Plus in) wire feeding the circuit.
This to prevent any current flowing back to the motor (and to prevent cheating).
In a diode the current can flow in just one way, this is indicated by a silver ring on the diode.
The wire from the motor must be connected to the other side.
Step 2
During the races the track voltage is ±20 volt. This is of course far to high for the l.e.d's used as lights.So we use a voltage regulator to bring down the voltage to 6 volts.
The regulator has 3 pins: The bottom pin is the positive in, connect the wire coming from the diode to this pin. The centre pin is the common negative, connected tis pin to the to negative wire (-) leading to the motor. The top pin is the positive out.
Step 3
To prevent any voltage oscillations 2 small capacitators are connected to the + in and +out pin of the regulator. The negative of both capacitators is connected to the center pin of the regulator.
At the top pin (+ out) you now have a stable 6 volts.
Step 4
To keep the lights burning under braking, a small rechargeble battery is included in the circuit.
It is best to use a small 47 Ohm restistor in the +out wire off the regulator (R1 in the drawing) This will prevent the battery from draining power from the motor while charging.
After the resistor you should have 5,5 volts.
Step 5
Last step in the circuit is the rechargeble battery it self; the Goldcap. You should use one of 5,5 volt, 0,2 or 1,0 fahrad (smaller value=smaller and lighter battery). The negative pin of the Goldcap is indicated by a black stripe on the cilinder. Connect this pin to the center pin(negative) of the regulator. Connect the positive pin to the resistor R1
Step 6
The wires on the right will lead to the lights, connecting them should be no problem but remember that you now have a 5,5 volts. You should calculate you resistor values accordingly.
