After a long time messing around with wires, soldering irons, multimeters and switches, a friend of mine and I have discovered the inner workings of the stampede. We were trying to find a way to add in a remote switch to the stampede and finally, we have worked it out.
Here is an image of the basic stampede circuit. This only details the motor and trigger switch, not the safety switches (they are simple on/off switches).
The red part is the switch which has 3 contacts. The dotted red line is the normally open connection, and the solid bar is the normally closed connection. When the trigger is pulled, the solid line changes from the shown position here to where the dotted line is. When open, it is easy to see the circuit created includes the motor, obviously causing it to turn. The important part that differs this from a simple on/off switch, however is what happens when the switch is in its normal position. In the normal position, a "short" circuit exists across the motor. This acts as a brake for the motor, stopping it the moment the switch is released. If this were a simple on/off switch (yes, i tried), the stampede will continue to fire after the trigger is released until the battery is disconnected, even on stock voltages. So, for this reason, It is important to keep this functionality of the circuit. That is the basic existing functionality and circuit explained (if you have more questions, ask them).
Now, if you are wondering how we managed to add in another, remote switch without compromising existing functionality, here is an image of our modified circuit.
Both switches in this circuit are exactly the same as in the previous circuit. Now what will happen, is when either switch is pressed and as long as either of them (or both) remains pressed, the stampede will continue to fire. You can easily add more switches, you just need to wire them in the same pattern seen here.
The switches you will need have 3 contacts. One of them will connect to both the other contacts (depending on whether the switch is pressed or not), usually located in the middle. One of them will connect to the middle contact when the switch is not pressed, and the other will connect to the middle contact when the switch IS pressed. These kinds of switches are used as safety switches in the stampede as well, except that only two of the contacts are used to create a simpler on/off switch. If you want to start adding your own remote switches and need additional help, simply ask away. Otherwise, I hope this helps any of you fiddling around with stampede wiring.
