Failed Salt Water Chlorinator Cell prompted me to document the circuit in my M140 chlorinator. Pretty simple…

I was able to rig up a test for the power supply using a couple of #44 bulbs and a resistor.

Yup,  working fine.  Interestingly: the failure mode for the old cell is that it appears to have a “diode” like short between the center plate and the sense pin.  I can only speculate that the calcium build up has caused this to act as a “diode”?

SRC is S2065J

Diodes are: 1N5404
