Hi there.

The shorted phone cord is only for diagnostic purposes!!!!!!!!!!! You only do it to see if the flow switch is bad. If you left the switch closed all the time, the SWCG would generate chlorine when the system is off - this would be VERY BAD!!

To see which wires need to be spliced together to bypass the switch, look at which 2 are wired on your existing plug-in (it's a black wire and a red one - I think they go in the center 2 slots).

Without an obvious nick in the wire, I'd suspect the fault is at the switch, try wiggling the wire and see if the 'no flow' light starts blinking.
