Thanks for posting the link Richard and all else..
In the Morgan world it does seem that battery charging systems are perhaps much as they have been for quite some time and thus charging and jump starting processes likewise are pretty well standard.
However I suspect quite a few of us or family members may have more modern vehicles which may suffer a flat battery situation, whereby using Morganesque procedures to charge or jump start the car could perhaps cause damage to the vehicles charging system, thus perhaps best to check the vehicles handbook, where you may find that the manufacturer has provided an entirely separate earthing point remote from the battery negative terminal to be used for the connection of the the charger or jump starter cables negative lead.
On some modern machines the battery requires to be coded in thus re-setting the charge control ECU to adapt it`s output from that of an old battery to better match the requirements of the new replacement. It would seem some of the gubbins relative to the monitoring process, is directly connected to the negative battery terminal, thus supplying an additional and external voltage to the neg terminal may confuse the on-board systems..?
Apparently on some modern vehicles a replacement battery if not of the correct specification, can not be coded into the vehicles systems to ensure full operation of all on board systems....!
It seems things may have moved on a tad from the needs of my wonderful old carb fed Morgan`s needs and wants... (-:
Having spent a proportion of my yoof trying to squeeze the very last volt out of a battery fitted to a variety of cars and m/cycles, things were so much simpler back when there was a starting handle available, and if not a push to get things going, or in the case of a m/cycle a run alongside and jump on would do the trick, better still if the sparks were magneto generated..... I suspect the term jump start, may well have been derived from the starting acrobatics of m/cyclists...?
These days and with modern vehicles it seems the life expectancy of some Advanced Glass Matt batteries may be circa ten years, whereas I used to replace my old style lead acid batteries at circa 3 years as a form of insurance to hopefully avoid issues.
Just thinking in type, I am no expert, and as ever more than happy to be corrected if you think I have got anything wrong..
