How to test transformer on furnace

Discussion in 'HVAC' started by jackb@sunflower.com, Dec 5, 2006.

    I have a humidifier installed on my furnace. I have an electronic 24
    volt water valve that shuts on and off when the pacific transformer
    class 2 sends the voltage.I have a multimeter to check the voltage at
    the transformer to see if it is working properly. There are two wires
    connected to the transformer going to the electronic water valve.I
    tried connecting my multimeter one lead to each wire but have no
    reading. I know the valve is working because when I disconnect the wire
    at the water valve the valve closes.How do I properly connect my leads
    from my multimeter to the transformer to get a reading?I am trying to
    determine if the voltage is shut off or is letting some voltage leak
    by.The reason for all of this I installed a new water valve and when
    the water valve shuts or tries to shut it is making my water line
    vibrate vigorously. I guess the main thing I want to know is how to
    check the voltage at the transformer.
    Thanks

    Where would you suggest I start to look it up?

    From a Google search: http://www.plastomatic.com/water-hammer.html . There
    are many other finds by google on this subject

  4. Isn't this a bit basic stuff to asking on a HVAC news group? I'm not
    sure I can explain it over the internet. You'd be better served to log
    onto www.google.com and type in "using a volt meter" without the
    quotes.

    Close your eyes and then touch both wires onto your tongue.

    No effect= Zero voltage is present.

    Major tingling affect and even lights up the backside of your eyeballs quite
    a bit= appx 24 volts.

    Lights all suddenly go out and you wake up at the pearly gates= YOU PICKED
    THE FUCKING WRONG WIRES.
