magician59 will become famous soon enough

There should be continuity between the two large terminals (red wires), when cold. If this is your first time to check for continuity, you will want to make sure you disconnect at least one of the wires from the component you're checking, so that you won't read anything misleading rom the rest of the system. If any of the thermostats is open, we like to recommend you replace them all as a set, so you won't have to do the same too soon (much like replacing your car's headlamps).
