That explains why my E38 BMW 740 Sport has jump lead terminals under the bonnet when the battery is in the boot and not easy to get at. I'll start a thread on the 7 Series forum and find out some more as my alternator seems to be working overtime with the characteristic whistle as though it's working hard.
That'll be a bugger if it ever goes wrong - it's buried deep in the front of the V of the engine as it's
cooled by water at around 88 dec C. How hot can the bloody thing get ?!?
