    Need help troubleshooting pcb relay

    Ok..by the way when I am testing I am putting probe on a known good ground and then other pin one one side of coil...then I record my 12vdc...then I do the same thing with the other side and get 6vdc...just making sure I am doing that right and I shouldn't be probing both sides of coil at the...

    If it doesn't read 12vdc on both pins like in my case (12vdc one pin and 6vdc other pin) does that mean I need to track down the other side maybe bad transistor or something? Or does it mean the coil itself has too much resistance and replacing the relay should solve this?

    Need help troubleshooting pcb relay

    Yeah it is a SMIh-s-112Lm Not sure on the specs.... So both pins of coil side should be close to the same vdc? If I am seeing 6vdc on one end and 12vdc what does that typically mean? I always thought one side of coil is ground and other is the power...

    Need help troubleshooting pcb relay

    I am troubleshooting a relay that i think is bad on a circuit board for a wine cooler.... I am getting 120 vac to one leg of the load but not getting 120 vac to other leg which gives power to the compressor... I am trying to diagnose if the relay itself is getting the correct voltage on the...
