    There is a short somewhere. When I have had this sort of problem I have disconnected stuff til the culprit is found.
    The water pump could be the obvious choice.
    The easy way would be to get it checked out by an Electro diesel mechanic.

    Just a few ideas,
    Is the main switch a earth leak switch? if so would trip if any of the power side is leaking /shorted to earth.
    The switch itself could be faulty.
    If you pull the fuses and replace them one at a time or disconnect circuits till there is no trip then re instate them one at a time to isolate the problem.
    Let us know how you get on.

    What is actually tripping?

    Normally 12v protected with fuses.
