****o All. We have a Richdel Sprinkler system that has a short in the #2 valve. We have tried the #1 selenoid in the unit & It works. However, when an installed new selenoid was tried the valve blew the fuse. We tried to bypass the #2 wire & hooked it up to the #1 to see where the short was. It still blew the fuse. HELP. Thanks Terry
