    Hi everyone, has anyone had all exterior lighting issues on their Cat? I recently purchased my first Catalina - 30 1978 she's had a few lighting issues. Anchor light is out since purchase Stern light recently burned the casing and went out. Port and starboard lights worked for a few days then went out..replaced bulbs but no go. Steaming light went out, and burned out replacement within 10 min. After third bulb replaced but not working at all.

    Would it be coincidence to have to replace all the fixtures or could this be another problem? Has anyone had any experience in this? And does anyone have advice in a good all around electrical book for beginners to advanced? Thanks for your thoughts!!

    Sounds like a serious wiring issue.

    Charlie Wing's Boatowners Illustrated Electrical Handbook is one of the best.

    How much voltage do you have at the sockets? Shore power plugged in or not?

    This sounds like excessive DC voltage at the sockets. Maybe an overzealous battery charger? Definitely measuring V at the sockets is essential as Justin mentioned.

    If you have the original switch panel, chances are in addition to whatever else, you've got a mess behind it, and maybe even an intermittent AC short to the panel the way the bulbs are blowing. Before removing the switch panels, DISCONNECT THE SHORE POWER CABLE!

    Different boat; different manufacture, but I have had issues in this boat and some others with both the sockets and feed lines of the stern and bow lights. The wires on the bow lights are joined somewhere in the run, so it's one feed of course. I found the wires corroded well under the cover. The second round, the corrosion was where the split was. The sockets also failed one at a time. On the stern light, it was the socket and its connector. So, the point is that these may have failed independently (your bad luck) or you have a voltage problem as suggested. I suggest you check at your panel first and compare that to the sockets to compare. Some drop at especially at the bow (because of the long run) is normal.
