When doing anything electrical, I always take a picture before I start removing wires. It has saved me a number of times

   I'm on the boat reconnecting the engine instrument panel. I left the
   manual and wiring diagram at home!
   Basic connections seem simple enough matching colours on the block
   connector
   But when I turn the key there's a short and the engine fuse blows
   Multimeter diagnosis shows that the thick purple wire seems to be a
   ground wire and thus I figure I may have midwifed by key switch as this
   connects the thick red (12v supply) to the thick purple and thin purple
   with black stripe
   The latter obviously supplies power to the engine instruments
   I assumed the thick purple from jeyseitch connected to thick purple
   from engine loom at chocolate block - hence the short
   So what DOES the thick purple connect to and why is it there as well as
   a thin black ground wire?
   Very confused!
