Minor electrical help needed

First, ensure that the bulbs are good. There are two wires on each bulb. one is the 12V lead that, as I recall fed from the tail light. the other is grounded to the trailer. since your trailer tail light is working you most likely have a bad connection in the power or ground leads. They are all in the area of the tail light. Examine them visually and I bet you will find the problem.

There is only one black wire going from the marker light to the plate light. How do I test this with a volt meter? And if any one knows how to remove a scratch from the windshield, that would help also. Thanks Ed The marker lights and license plate light are on the same circuit as the tail light. If the tail light is working, you either have a bulb bad or a bad connection and/or ground at the lights that are not working.Jones Trolling Motor Services870 773 3474Motorguide/MinnKota/PowerPole/Lowrance/Humminbird
