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.
The first things we need to do are check the compressor electrically and make sure it is safe to start; after making sure the compressor is safe to start, we need to reconnect it and see if it will start — the start assist (PTC) device may be defective; and when and if the compressor starts, we need to give the system a thorough check up to see why the technician was even doing what he was doing to cause him to disconnect the compressor,” Bob replied. “How can we make sure the compressor is safe to start?” Tim asked. “We want to make sure that it is safe to apply power to the terminals, Bob said. ”Use the Ohmmeter set on RX10K (10,000 Ohms). Second, fasten one lead to a good ground, scrape any scale or paint off the suction line, for example, and firmly hold the lead to the bare spot. Then, touch the other lead to one of the compressor terminals and record any reading. There should not be a reading. If there is a reading, the compressor has a ground circuit in the compressor. A circuit from the motor windings to ground. ”To illustrate how your meter works, you should be able to read a slight reading through your body if you hold one lead in each hand,” Bob continued. ”
