testing transformer on furnace

[mapman]

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
Jack

Heh, the valve's doin' the Jitter-bug.

Like to help but site rules are site rules.

Each of us here takes pride in knowing safe meter usage and familarizing our selves with any new instrument that comes into our possession.

I will say this, don't use the humidifier until the chattering valve has been assayed and corrected.

I don't know how it is wired into your furnace electrical,
but it is not worth taking a chance on causing a burn out of an expensive part.


Please, don't fix until it's broke. Call a good company to look at it.

It won't cost as much as you fear and your furnace will thank you.:)
