I was fixing the sprinklers today,cleaning them out and replacing a few.

The bore was working ok all morning while I was re-checking the sprinklers,(turning bore on/off manually)then the last time to make sure everything was ok,the bore won't turn on,and keeps blowing the fuse.

Replaced the fuse wire,and same thing- blows the fuse straight away.

So looks like I need to get an Electrican to come and have a look.

Thanks for any help.
