Found some time and thought an update was in order. All the lights on the accommodation block, interior, navigation, stern and searchlights are now installed and working. I had a problem with the interior cabin lights which worked fine until I put the cabin roof together when they went out! All sorted now, they were shorting out on a bit of exposed wire which is now insulated solving the problem. I had a small problem with my red navigation lamp that stopped working, somehow I had managed to break the positive leg right at the base of the LED, couldn't see it until I dismantled the set up, new LED in place and working well.
I have 4 circuits, 1 the navigation lights, 2 interior lights, 3 searchlights, 4 stern light. All fed through individual resistors for each circuit and a small toggle switch that allows me to choose which lights to have operating. Many thanks for all your help, the links to resistor calculators were a great help.
I need to finish work on the hull now before I can install the mast lighting that will be on two circuits, again manually switched, I have tested the circuits and all works fine. Just hope they still work once installed as they will be a b***er to change out.
Thanks once again for all the help
