Car isolator
Battery isolators are best seen as the distribution point of an automotive electrical system. Generally built with diodes, isolators ensure that charge is evenly distributed between multiple batteries and the alternator.
i have full grid, 2 messages and the bits under the grid filled in, but don't know how to apply the instructions...so that i can do some blue shading ??? Help please
saladdodger, the letters 'removed' are to be imagined piled on top of each other - the triples are 1 higher than the doubled (3 letter) sequences which are 1 higher than everything else. So, there are only 8 high areas.
Anagram the doubled letters for the 3,9 (Darwin is relevant) and the tripled letters for the 4 (a general term for the first one).
saladdodger, for example the 3 'i's at the end of column 3 makes it 3 storeys high - the duplicated 'iss' in the 3rd row from the bottom makes it 2 storeys high (everything that is single storey is vulnerable).
