    Some images would help The item with Durite on it may be a Voltage Sensitive Relay.

    Have tried Calcutt boats?
  3. Keith M
    Have you also considered using a Maxi Fuse for the lower currents ANL fuses are supplied as low as 20 amps.

    There is at least one air-cooled Lister engine where the engineers and apprentices train.

    I second Cheshire Cat

    JD Boat Services of Gailey I have always found to helpful.

    I do own two insulation tester, one of which is design for low voltage AC and DC systems. I also have a Portable Osiliscrope for generator and inverter output testing.

    I started my working life with the GPO later become a member of BT I regularly used an AVO during my days with BT

    yes, some of my own meter's are fluke they are used daily and also calibrated annually. Safe isolation equipment and earth leakage tester I use Martindale. I also some Kewtech and megger testers Different tester for different applications.
  10. Keith M
    Kewtech make a nice clamp meter at a reasonable price

    I think the unit is shutting because of the high output voltage If the output voltage was reduced it may function correctly
  12. Keith M
    It is possible that the output voltage of the charger has been re-configured What part of the UK is your mooring I may be able to help?

    If you go back to about 2016 Mastervolt did produce a chargemaster 12 /100 with at least two outlets maybe three
  14. Keith M
    Is this unit a Chargemaster or a Chargemaster plus? If a chargemaster plus was the activation steps followed? If the unit is under two years old it should be cover by Mastervolts warranty, who undertook the installations and this should be your first call.
  15. Keith M
    It may have been a poor fitting plug or a substandard plug and socket

    I am sorry but I have to disagree During all of my AC training which is still ongoing, I have always been told 20 mA has and can be fatal, this is why certain installation requires the use of a 10 mA RCD and normal domestic installation have 30 mA
  17. Keith M
    Within an AC circuit with the voltage at 230 volts, 20 mA is enough to upset your heart.

    A selection of wago connectors should be in every boater's onboard repair bits.
  19. Keith M
    I would use a wago type connector this will give a significantly better termination.
  20. Keith M
    It is difficult to keep track of all of the posts
  21. Keith M
    Yes, that is correct will 12 amps be enough?
  22. Keith M
    It is very poor practice to take a 12-volt supply from a 24-volt battery bank, always us a DC / DC converter 24 in 12-volts out. It will just wreck batteries. I have worked with marine electrical installation for more than 30years I have never come across the Vanner unit. As an aside looking at the images of the batteries are the interconnecting cables the same cross-section area.
  23. Keith M
    You could just buy the metal screw at Midland Chandlers. They cannot be that expensive?
  24. Keith M
    What for the hire boats to arrive?
  25. Keith M
    I have always been taught that the hot water always goes to the top of the coil and as the water coolers it falls to the bottom of the coil to return to the engine.
