Bad flow sensor on chlorinator

[Pool Clown]

Just so you have accurate information...

IF the unit is wired to the pump, the unit will shut off when the pump turns off, However, if the pump were to loose prime (while running), the unit would continue to run. The shorting of the flow switch should only be done as a test, and not left to operate like that.

The flow switch should be removed, and the two wires that waste spoke of, tested with an ohm meter while contacting the switch manually. When removing the switch, note the arrow on the switch. That arrow should be pointing in the direction of flow when you reinstall the switch.

Note: As you probably already know, the flow light will flash for several seconds when first energized, and should show flow shortly thereafter.

Thanks. So how does the switch work exactly? Doesn't appear to make physical electrical contact on the part that is exposed (the round post doesn't conduct electricity). Is the switching mechanism actually inside the top? I can't get it to read short when I manually "close" the switch while connected to the wires on the jack...
