Looking for some help in trouble shooting a service call for a blown 1.5 fuse, the lady has already opened the controller (esp-8) but it did not look that disturbed. I replaced the fuse set the clock and manually start zone 1, zone 1 starts. I manually start zone two, it starts without an issue. I manually start zone 3 and zone 1 starts then the fuse pops. Replace fuse and start over, I make it to zone 5 and zone 2 starts just before the fuse pops again. I want to eliminate the issue so I disconnect the common and zone 1; I connect my 24 and get an open green light but no water. I try zone two, green light no water. I try all 7 zones and no water. Puzzled I looked at the controller again and there was not a wire for a mv. I connect the controller again and go back to the same process new fuse, zone 1 starts, blah, blah, fuse pops. Even more puzzled until I notice a stripped wire in the multi strand when three others are not striped. I connect the 24 to the open line and the common and get an open red light. This starts to eliminate a mv, correct? So why would the valves not open when the 24 was giving me a green light and the zones would open by the controller with out a mv connected? The clock output test was good on all 7 zones. Could there be a short in the multi strand and if so should it not show up as a short red light on the 24??????
