Originally the wiring system had a number system, however over the years the system paperwork as disappeared and the systems the lifeboat needed during its working life are no longer needed so they are going to be removed to be replaced with a very simple system.
No manual to work too and the system is no longer used so all this system is going to be removed and an easy to follow system pt in its place.
The original system which is no longer needed now that it is going to be a river boat and just needs to start the engine on a 24 volt system.
Four volt meters a bit over kill
An over kill system which is not needed any longer
Now for the fun part removing all this wiring and making it a simple to use system
