C42 Indicator Light
GeorgeIt sounds to me like the light you are referring to is the reverse polarity light, especially since it is on the 115 volt side. Depending on how your boat and panel is wired, it MAY only light if you are connected to shorepower. What I mean by this is that when you connect to shorepower, it MAY NOT light unless you have reversed polarity. In this case, having it NOT light is GOOD. (Reversed polarity is when the incoming power from the dock has the hot and neutral wires wired backwards.)Some boats have two sets of lights, one that says polarity is OK, and the other if it is not (once you are plugged in). I do not know what kind of setup you have. Sometimes the lights do burn out. If you want a backup, just go to a hardware store and buy a reverse polariy tester, hook up to shorepower, turn on your breaker and plug the tester into an outlet. They cost around $10, or you can have the light replaced, if, indeed, it is out. It may not be broken at all. I suggest you either find another C42 owner and ask him, or check with someone local who you know who understands electrical systems and ask him (boat size does not matter here), or check with a local dealer. The Catalina 42 Association website may be of some help to you, also.Good luck,Stu
