A Method of Tracking Down Low Voltage Shorts and More

One of the methods I use to chase low voltage shorts. Couple useful things here. How I handle batteries constantly being put in a stat that utilizes a common. No matter how often you tell them not to. It just delays them from realizing they have an issue, or a breaker trip, and delays some young techs on diagnostics. We also trace a bit of wiring in the wiring diagram. When trial and erroring the stat wires, there is no right or wrong, though most commonly it is found in the red wire, but I myself always save it for last. No rhyme or reason other than I don't want it to be the red, so maybe due to dread. So I guess there is a reason.... and also a rhyme. But weed eaters are color blind! After pulling on wires and losing the active short, I show a trick I learned from watching a video, to use your megohmeter to assist in locating shorts. Unhook both sides of what you are testing, check it to ground. Hope passing this info along this proves helpful! #hvac #hvacapprentice #hvactechnician #hvaclife #hvactroubleshooting
