I have been given a small single phase 3 speed Grunfos circulating pump that will be ideal for our outside pond if I can get it working.
It apparently got moisture into it's terminal block and had a catastrophic flash over which frazzled the connections and blew off the terminal cover.
The above mudmap is what is shown when I checked it with a multi meter, None of the internal coils seem to be down to earth.
Also a 5uf 400v capacitor came with it.
Anyone have any idea how it should be connected to the capacitor and mains to run at maximum speed?
Any help will be appreciated.
