I need a way to check for wiring problems. I want to do an continutity check at the valve but I guess I should do an ohms check. Do I disconnect the station wire from the controller and and then temporarliy connect it to the common making what should be a closed circuit. I read somewhere that you leave the station wire disconnected and check for the correct ohms. That makes no sense to me though because then you don't have a complete circuit. I have an ohms meter and I'm not affraid to use it.
