To replace, repeat the steps in
reverse order, paying particular
attention to the following:
a - Centre the electrode in the
positioning hole carefully,
otherwise the electrode may
break;
b - Ensure that the left hand and
right hand electrodes are
located the correct way
round (facing each other), to
give the correct spark gap;
c - Check that the cables have
been connected correctly;
d - Check that the rubber gasket
seals the cable/ electrode
connection point completely.
