Need more information to help you.
Leave the system as installed...don't move wires yet. Go buy some fuses first.
When you operate zone 1 it works
When you operate zone 2 it blows fuse?
If it only blows fuses on zone 2, chances are it is bad solenoid on zone 2...however try this first:
Remove station wire from zone 2 and don't hook it up to anything....then try to turn zone 2 on manually with a good fuse...does it still blow the fuse?
If it does, what type of controller is this? It is quite possible that the timer has a short in the panel.
If it doesn't blow a fuse, either the solenoid is bad...or you have a direct short in the wiring.
To avoid all this trouble...call a sprinkler pro in your neighborhood, if you need help finding one, maybe we can help...most of us know guys in many areas that we can refer you to.
Expect to pay between 45 and 85 for him to show up....and 40-60 per hour after the initial service call fee, plus parts. Good luck,
