Why is my orbit/watermaster fuse blowing with brand new solenoid?
Turns out that new solenoid was a &quot;13V DC solenoid for battery operated timer&quot; and my timer is a watermaster &quot;24v AC&quot; wired timer.
Which apparently causes fuses to blow.  Using the right solenoid it works now.  I had better luck finding them at Lowes, YMMV, they do exist anyway (small head 24V solenoids).
