    Many years ago I had a similar problem with a brand new battery, start the car and it worked fine. Next start - clunk. Next start - fine.
    The battery was replaced with another new one and it all worked OK after that.

    That is correct. Although I would check the resistance back through the engine block. In either case, the resistance should be at zero or very close to it.
    Do not concern yourself with the internal resistance of the multimeter when checking resistance. It has no bearing on the value of resistance it displays.

    I should add that this test is probably not needed, but no harm in doing it.
