Thread: Nav lights

Whilst you guys are on the subject of tinned wires, when doing my apprenticeship many years ago I was taught to use 70/30% solder for all electrical gear EXCEPT marine. Wehad to use 60/40% because the 70/30 was too brittle and gave way after a few years with the vibration. The 60/40 is obviously softer but doesn't fracture with boat vibrations. I changed all contacts on my boat and never had an electrical issue all the years we had it.
