ok thanks for the help so far, i have been out and tested the
feed from the multiplug and there is no power, so im assuming
the fault is somewhere else, i cannot seem to trace where the large
red wire goes to, does this go staright to the battery?
im on about the permanent live to the ignition switch, if i run a
live wire to either side of the multi plug or straight to the ignition
switch then it all works fine.also the plug has no signs of damage
