That's the way I remember it, Howard. Meanwhile, I will share what one of
my 6th grade students advised. She was not a very scollary youngster. Most
of her learning came from The Grand Old Opre which was broadcast on WLS in
Nashville. "The best way for a man to get along with his wife is to keep
his wallet open and his mouth shut." Not how my wife of 59 years and I
manage but that's what the student offered.

>>
>>
>>
>> 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.
