To answer question #1: Probably. It is most likely that you aren't ever getting the battery up to full charge and that is degrading it over time because you are drawing from deep in the plates as opposed to surface pull on the starting battery. For a better understanding of this I would suggest you get Nigel Calders "Boatowners electrical and mechanical manual". He has a very thorough description of batteries, their loads, and what happens. I think I have several of the original bulbs on Pyxis (at least they have Kanji characters on them) and they are all 20w. That could be causing your hot sockets. As far as a short goes the answer is: "You might" and "not necessarily". You need to get an ampmeter on the battery and find out what the pull is when the lights are on. With two cabin lights at 25W each it should be just a little over 4A. Anything more would indicate an electrical leak somewhere which is not quite the same thing as a short. Shoot me a PM if you want to discuss it further.

It's for RV's (my new adventure) but the same principals apply.
