How To Test A Potential Relay Part 1 Youtube Potential relay operation and testing. In this hvacr training video, i go over how the potential relay works and how to troubleshoot it! i show the wiring and contacts at 5, 2, and 1. i explain ho.
How To Test A Relay Youtube Watch tim as he outlines the steps to diagnosing a faulty potential relay on a residential ac. is the indoor fan operating? is the outdoor fan operating? is. November 3, 2002. a simple ohmmeter is all that is needed to troubleshoot a potential relay. after taking all of the connecting wires off of the potential relay, measure the resistance across the 1 and 2 terminals. the resistance should read close to zero, since there are normally closed contacts between terminals 1 and 2. The potential relay is normally closed, and it opens when a sufficient pickup voltage is present between the 5 and 2 terminals on the relay. this pickup voltage is the potential (voltage) that exists in the start winding when a motor gets above about 75% running speed. it is generated in the start winding by the motor itself, not the capacitor. Operating and troubleshooting potential or voltage relays. by john tomczyk. figure 1: the potential relay consists of a very high resistance coil and a set of normally closed contacts encased in a small plastic housing. figure 2: the relay coil is wired between contacts 2 and 5, while the normally closed contacts are wired between contacts 1 and 2.

Step by step guide on testing a relay. 1. identify the relay terminals. before testing the relay, you should have a clear idea about the terminals of the relay. the first step is identifying the primary side or the coil terminals. for an automotive relay, the coil terminals are 85 and 86. 5 pin relay pinout. To test a 5 pin relay using a multimeter, set the multimeter to measure resistance and connect the probes to the 85 and 86 pins. if the meter displays a resistance reading between 50Ω and 200Ω, the relay coil is good. activate the relay using a 12 volt battery and jumper cables, then measure the resistance between pins 30 and 87.
