Electrical connection between conductive elements

A method of forming, removing and checking upon an electrically conductive connection between one or more electrically conductive elements (2, 6) which are coated with a non-conductive coating (7), wherein an at least partially electrically conductive pasty medium (8) is to be, or already is, located in a region (12) between the electrically conductive elements (2, 6) at regions of the electrically conductive elements (2, 6) which are substantially free from any non-conductive coating (7), characterized by:

• providing one or more channels (21) from the outside of one or other of the electrically conductive elements (2, 6) to the regions of the electrically conductive elements (2, 6) which are substantially free from any non-conductive coating (7) and either:
• a) injecting the at least partially electrically conductive pasty medium (8) through the one or more channels (21) to the regions of the electrically conductive elements (2, 6) which are substantially free from any non- conductive coating (7);
• or
• b) injecting an appropriate solvent through the one or more channels (21) to the at least partially electrically conductive pasty medium (8) in order to dissolve the at least partially electrically conductive pasty medium (8) and allow this to be flushed out of connection;
• or
• c) looking through the one or more channels (21) in order to ensure that enough of the at least partially electrically conductive pasty medium (8) is present in the connection to form an appropriate electrical connection;
• or
• d) injecting pressurized fluid through the one or more channels (21) to gauge whether the region holding the at least partially electrically conductive pasty medium (8) are isolated and air and/or watertight.
