[TR] Off topic electrical question

[John Macartney]

If we're talking about modern cars, I'd agree there's probably no need to
isolate the battery for re-charging. 
But with older LBC's with (relatively)
low output alternators and with perhaps not the same level of circuit
protection when used in conjunction with modern high output chargers,
disconnecting the two terminals is hardly inconvenient, is it? For the sake of
perhaps an extra minute before and after setting up the charger, fully
disconnecting the battery is hardly onerous. Well, it isn't for me - but then
I'm probably old-fashioned and I *know* without doubt that a full
disconnection will only have power going in to the battery which is what I
want. Why run the risk of wrecking costly electrical equipment when a little
preparation beforehand will save that inconvenient extra spend in replacing
things that get 'blown'?
