Before we begin, look at your bodycord. We're going to call the pin that is separate from the other two, the Outside Pin
. The one next to it will then be called the Middle Pin
. That makes the pin on the opposite side the Inside Pin
The wires in the bodycord all go straight through. When we take measurements we will be testing the Outside Pin on one end of the cord with the Outside Pin on the other end of the cord. Similarly, we'll test the two Middle's and the two Insides. When we test them, we want to make sure we have low resistance, or at a minimum continuity.
For example, when I tested the bodycord below I got:
- Outside-Outside = 0L (no connectivity)
- Middle-Middle = 0L (no connectivity)
- Inside-Inside = 0.4 Ohms (connected. OK)
From that information, it's no surprise this cord didn't work on the fencing strip. Two of the three pins are not able to transmit any signal back to the machine.
