1990 80q battery problem -- it ain't the battery

[rob hod]

  I'm afraid my experince may not help you much here, but I had a wry laugh
at my own expense at the weekend;

     My garage queen 87 CGT had a poorly battery for some time, but usually
the enigine stumbled into life the couple of times a month it was asked to
perform. On saturday I went over to my parts supplier for some parts for the
100 Avant. Round trip some 30 miles. When I got back I went indoors for half
an hour before going back to the car to put it in the garage. Battery was
completely dead. I couldn't beleive it, especially after a slightly longer
run than it usually gets of late!  I finally sussed out that (being a hot
day) the cooling fan had been cutting in several times while I was indoors
and completely finished the battery for me. Like terminally. Ho hum. It now
has the new battery that it should have had six months ago. As I said maybe
no help to you, but somewhere in all this there's a moral..

   PS the battery was so weirdly deranged that if I held the ign key in the
start position dash lights would all extinguish while the rev counter needle
would do a kind of dance of death round the gauge..

  Cheers,

rob
