>> Hi, all.
>>
>>
>>
>> I am sure that, to some, this question might seem to be very
>> elementary, especially for someone like me who holds an Extra class
>> license. So, please bare with me, and understand why I am asking the
>> question. As a college professor, I always try to teach my students

>> procedures and/or concepts and the reasons behind them. I also stress
>> that true learning involves being able to apply what you have learned
>> to real life situations.
>>
>>
>>
>> Anyway, here's my question:
>>
>>
>>
>> Earlier this afternoon, my XYL and I were in the process of getting
>> our summer camping trailer winterized for the season, and taken to a
>> local facility for winter storage. As we worked, it came time to
>> disconnect the house battery from the unit, so that it can be put on a
>> trickle charger during the winter months.
>>
>>
>>
>> Before we disconnected the battery, we were discussing the best and/or
>> safest procedure for doing so. We never worried about this with the
>> drivable RV we used to have, because it was always kept in our
>> driveway and plugged into our main house power all winter.
>>
>>
>>
>> Anyway, my proposed approach was this:
>>
>>
>>
>> When disconnecting the battery, disconnect the positive side first,
>> and then the negative. The idea here is that you always have the
>> negative or ground connected when you're working with the battery.
>>
>>
>>
>> When re-connecting the battery, I proposed connecting the ground
>> terminal first, once again, to give you a ground to start from, and
>> then connect the positive terminal last.
>>
>>
>>
>> My XYL's approach was the opposite:
>>
>>
>>
>> She argued that when disconnecting the battery, disconnect the
>> negative terminal first, and then the positive. . When connecting,
>> connect the positive first, and then the negative.
>>
>>
>>
>> As a smart person who has much faith in my XYL's judgment, I decided
>> to go along with her proposed approach, and happily, we are both still
>> here to talk about it.
>>
>>
>>
>> However, I know that I have connected and disconnected many a battery
>> using my initial approach, and I've survived that as well. Perhaps I
>> just got lucky, but I always thought I was proceeding with care, and
>> with the correct procedure.
>>
>>
>>
>> Once again, I hope nobody minds this question, but I consider everyone
>> here to be knowledgeable on many things, and I trust that you will all
>> be able to go with the idea that the only stupid question is a
>> question that goes un-asked.
>>
>>
>>
>> Your wisdom on the topic would be most appreciated.
>>
>>
>>
>> Thanks for listening.
