Whenever possible the model number on the old relay should be used when ordering a new relay.
Potential relay troubleshooting.
The resistance should read close to zero since there are normally closed contacts between terminals 1 and 2.
Potential starting relays consist of a high resistance coil and a set of normally closed contacts.
The relay does the same thing.
This video explains the terminal arrangement of a potential relay how to wire it up and how it works.
The relay coil is across terminals 2 and 5 while the relay contacts are across terminals 1 and 2.
Remember short out the start cap used above.
Replacement relays can be cross referenced for different manufacturers using convenient tables via the internet.
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.
After taking all of the connecting wires off of the potential relay measure the resistance across the 1 and 2 terminals.
Potential relay operation and testing.
All you have to do is touch the ends of the.
I ve used this procedure many times.
My paperback and e book.
A simple ohmmeter is all that is needed to troubleshoot a potential relay.
A simple ohmmeter is all that is needed to troubleshoot a potential relay.
Troubleshooting of a potential relay can be done with an ohmmeter.
Knowing the sequence of operation for this type of starting relay can help you diagnose confirm or rule out certain service problems.
The above procedure simply mimics the action of the potential relay.
It s probably a bad potential relay.
