did you replace the transformer?
Was transformer a multifit or OEM replacement?
All unused leads capped separately?
What 2 colors did you hook up on primary side?
What model transformer ?
And are you measuring for 24v wire to wire or wire to ground?
orange and white
wire to ground
i was having computer issues but i think its good now Are you still here
Last question....when measuring primary (220)...are you reading each wire to ground or wire to wire?
you said you tested transformer in wall outlet...but that would be 115v. We need 220 and I hope you used the 2 wires on primary for 230v.
Now you need to measure supply wire to wire. With 220 you must measure wire to wire because it is possible to have only one leg and be reading that same leg on both sides.
Verify wire to wire for 220v
Verify primary wires on transformer are for 230v
Then check 24 v side wire to wire and not ground
let me know results
