The coil is wired between terminals 2 and 5 with the contacts between terminals 1 and 2.

Potential relay troubleshooting.

A simple ohmmeter is all that is needed to troubleshoot a potential relay. It s probably a bad potential relay. The relay coil is across terminals 2 and 5 while the relay contacts are across terminals 1 and 2. Potential starting relays consist of a high resistance coil and a set of normally closed contacts.

I ve used this procedure many times. The relay does the same thing. The above procedure simply mimics the action of the potential relay. The start cap is momentarily applied to the circuit then quickly disengaged.

My paperback and e book. The resistance should read close to zero since there are normally closed contacts between terminals 1 and 2. All you have to do is touch the ends of the. Knowing the sequence of operation for this type of starting relay can help you diagnose confirm or rule out certain service problems.

Replacement relays can be cross referenced for different manufacturers using convenient tables via the internet. Troubleshooting of a potential relay can be done with an ohmmeter. Whenever possible the model number on the old relay should be used when ordering a new relay. This video explains the terminal arrangement of a potential relay how to wire it up and how it works.

When used with a run capacitor a 15 000 ohm to 18 000 ohm 2 w bleed resistor should be attached to the start capacitor to prevent possible arcing when the relay contacts open. A simple ohmmeter is all that is needed to troubleshoot a potential relay. Remember short out the start cap used above.
