    Hi all..

    I have found the relays on the pump itself and the wiring to them have 12v

    Is this a case of changing relay and job a good un..

    Did try a relay out a legacy as pins matched up but part number didn't. Sadly this didn't solve anything

    Any advice welcome.

    Take the relay out and test it. It is easy to do. 9v battery and a multimeter is all you need. How many terminals are on the relay?

    Chances 2 relays dead though?? Or was the legacy one with wrong part number never going to work.

    Highly unlikely you've got two broken relays. Relays are likely the same. If you know the part numbers I could confirm whether the operation is the same

    Any further advise.

    What readings to expect on each pin be handy.

    Believe pin 85 is earth.
