Good day, all. We have a 1987 P28 which has only just lately started popping the nav lights breaker. Other than the panel piilot light, there are 2 wires (actually 4 but spliced to two connectors). The grey wires are the lights and they alone will not pop the circuit. The white wires will, tho I have no idea what it is they run to. Oddly enough, if I connect the white line to another breaker, it remains closed. Short of having an assistant yank on the bundle while I crawl thru the head, lazarette, etc, I'm not sure how to identify the culprit. Any ideas, P28 folks?
