Hello all,
an update:
We diconnected the FAV upstream, to see if the main pump would flow on SYS. It did just fine, so everything seems to work up to the FAV.
We disconnected the FAV power supply and connected a (charged) car battery (12V) directory to the FAV power pins , while using the SYS jumper. No spray: so the FAV is broken. To be sure, we reversed the connected as well, making sure that we feed the current to the right pole.
We then hooked up the fav power supply again and see if under SYS we would notice a power potential difference over the two connectors while connected to the FAV . We did NOT notice a potential, which we found odd.
We then tried it with the wire diconnected from the FAV. Again, no potential measures, as if there is no power from the controller.
In the last test, we disconnected the FAV power supply and disconnected the FAV input to the controller, and put the battery on the FAV side on the wire. Then we tried to measure a potential on the FAV input connecter on the controller side touching the copper connectors on the RJ11. We noticed a potential equal to that supplied by the battery.
Our conclusions:
- FAV is broken
- FAV wiring is not broken
- Possible issue with the power supply from the controller to the FAV as we were unable to record a 12V potential over the wire when on SYS.
Richard, i will send the FAV unit to you. Can you perhaps explain why we could not measure 12V out of the controller ? Is this some safety measure ? Is the controller talking to the FAV and if it doesn't get the right signal it does not put 12V on it ?
I'll use this address:
