Old as Dirt!
If a pin connector is what you need/want Google Four Pin Wiring Plugs. Chop off the old plug and splice the matched colored wiring to the new plug tail pieces. Maybe 30 minute repair.The four pin connector for my masthead light has one broken pin at the base of the mast. As a result the connector does not make good contact at the base of the mast. The broken pin is one of those split pins. I broke it by wedging a tiny screw driver into the split in the hopes of opening it and getting a better connection. In the process of doing so one side of the pin broke off. My bad! As a matter of fact some day I am going to list and tell the stories of all the repairs i have had to do that are self-inflicted. I think sometimes boats get a bad wrap of being expensive to maintain when all along it is idiots like me just breaking perfectly working stuff. Anyway I digress.
Now the pin with just one side remaining is way to small for the female end of the connector and the lights don't work. Short of ordering and soldering in a new connector, is there a DIY fix for this one pin? Thanks
