Black And Red Wires Positive Negative. Find the batteries and their terminals. One is marked positive the other negative. The electrode attached to the black electrode lead should be placed over the area that you require to contract under the action of the stimulator.
The positive wire for these systems is red and the negative wire is black. Electricity results from the flow of electrons. The red wire is usually positive in electrical circuits. The red one is positive the black one is negative.
If the multi colored wire is black and red the black wire is the negative wire while the red one is positive.
The green wire is also for data but it is the negative wire. One is marked positive the other negative. If the multi colored wire is black and red the black wire is the negative wire while the red one is positive. Electricity results from the flow of electrons. Very often we find ourselves striping wires cutting wires splicing or simply removing a cigarette lighter plug to then hardwire the wire.
