Interesting troubleshooting call yesterday. An existing Toro controller, a homeowner installed ECXTRA, which appears to be an updated Greenkeeper, showed a "FUSE 3" on the display, indicating a short on station 3. http://www.toro.com/sprinklers/timers/index.html I t apparently will identify shorts and bypass them. Two valves were wired to station 3, both shrub areas, and enough pressure and flow to make it work. (This was done after someone else discovered a broken or nicked control wire and didn't ant to run a new wire under the house...) Even after re-splicing the valves with Dry-Conn connectors, turning the controller off and back on again, it still displayed "FUSE 3". i read 13.6 Ohms at the clock (25 to 28 on all the rest) consistent with 2 Irritrol valves on one station (approx. half the resistance.) It seems like whatever I did, this controller interpreted it as a short. So, I ended up replacing the controller with an Irrigation Direct DMC. No problems after that. So, is it a problem with the resistance as identified by the other controller as I think, or is that controller just not designed for more than one valve per station?
