Where do the pins 3 and 4 go from the RJ11 Flow Switch Connector

[bshoefl]

Hello,

This is for a AquaRite PCB Board. I was using my multimeter to try to figure out where pins 3 and 4 from the RJ11 Flow Switch Connector go once they leave the RJ11 Flow Switch Connector. The flathead screwdriver test failed, I soldered all six pins of the RJ11 Flow Switch Connector together, and I still don't get Generating except for a few moments, mostly the output is the Red No Flow. If I can trace where pins 3 and 4 go to on the board, I have a shot at fixing the board.

Thanks,
Brian

Good morning Brian and welcome to TFP! Did you ever figure out where the pins needed to go?

It is highly possible the break is in the RJ-11 connector itself. Use a hacked tel cord and run a continuity test to rule out the connector. Then with the help of an Ohmmeter, trace the double-sided circuit on the pcb. It's been a while and I can't remember if pin 3 or 4 has the 5-volt dc tied to the micro-controller chip via a voltage divider network. When pins 3 and 4 are tied together, the 5-volt drops down to 3 volts and resumes normal operation. And that's all I have. Btw, what sw version do you have?
