Time for a service tech unfortunately.....there is a direct short in zone 7 somewhere...
Have you been digging lately?
Has the phone company or cable company or others been digging lately?
If you can find the area that someone has been digging lately, perhaps you can fix this yourself, but if not, a tech is necessary who has the right equipment to find broken / shorted wiring underground.
I have also seen broken/shorted wires show up where people stapled the wiring to the interior walls from the timer????
Just consider that the wire for zone 7 is making contact w/ either direct ground or with the common wire....or it has been wired wrong ?
