Having some issues with no rear turn signals or brake lights on my 1986 w250 pickup. The first puzzling question I have is why would I have intermittent voltage going to the fuel sending unit (key in "on" position) and the wire that leaves the fuel sending unit goes back to the rear lighting harness and also has intermittent voltage? Intermittent meaning you have voltage and then you don't and that cycle continues to repeat.
