at 30 ohms. You check this and it does measure at 30 ohms, therefore a good circuit. The result of your circuit isolation process is that you have identified that the short’s location is in the blue-colored wire circuit 2B. Part of good troubleshooting and repair goes beyond just fixing the issue. Akin to the process of using sod to “solve” a dead spot in a lawn, unless us you do something to prevent the instigating factor, the issue will reoccur. For exam-
ple, chewed wires can be reduced by protecting exposed wires with conduit (PVC or metal), and/or reducing rodent/gopher populations. Confirm that there is no exposed wire at any connection that the waterproof wire connect completely encapsulates the wire nut and wire housing. At the controller, only strip off enough wire to adequately attach to the terminal strip. Always emphasize to the installation/maintenance crew to carefully excavate when near control wires and, if they ‘bump’ (nick) a wire, carefully in-
