Technical Training Associates added a new title to its HVACR Troubleshooting series: ”HVACR Troubleshooting Fundamentals: Electricity & Wiring Diagrams Student & Instructor Package.” This HVACR electrical training package includes a 420-page spiral bound training manual, an accompanying instructor guide, and PowerPoint supplement. The book is clearly written and easy to understand, providing a basic foundation for learning how to use wiring diagrams and test equipment to troubleshoot HVACR electrical systems.
The largest reading was from 1 to 3, and would be the reading through both windings so that would be from 1 through common to 3. This tells you that the 2 terminal is the common terminal. “You have identified the “C” the common terminal as the number 2 terminal,” Bob explained. ”Now we know from process of deduction what the other 2 terminals are. The shortest winding with the least resistance is the run winding so terminal 2 to terminal 1 is the smallest resistance making the 1 terminal the “R” run terminal. The only terminal we have left is the “3” terminal and that makes it the start terminal. You can now take the red wire and put it on the run terminal, the white wire on the common terminal and the black wire on the start terminal.
