I sold my Soveriegn , and I am contemplating a water machine as I have told you guys in the past ..... I am considering an Excal or a CZ-20 or21 ......If i go the Excal route , I still have a brand new 10x 12 coil that might just fit the bill for a nice coil for the water ....What waterproof connectors have you guys been using for your water machines ? ......Is there a special schematic I have to follow to attach the SEF coil to the Excal or is it the same wiring as the Soveeign ? ......With the correct wiring it should work just fine ..right ? .........Thanks , Jim
