Hi all, I am trying to install a new transformer on my furnace and well the new transformer does not have the labels my old one did, COM , COM , 120v, 24v. Here is a picture of the transformer it only shows LOAD, LINE but doesn't specify which lead is exactly what.
Also I have attached a second picture of my old transformer.
Thanks for any help.
