Led on the 1000 is not so good an idea as the generator runs flat out all the time so the regulator and battery cook if power is not used elswhere

The regulator failed more often on UK bikes where we could turn the lights off, the generator itself runs at 100% all the time and the regulator has to safely pass all the un neaded amps/volts after the battery was fully charged to ground safely which causes a lot of heat, guess what most electronics dont like heat and excessive heat shortenes the life.
Never wondered why you can get aftermarket stators for the four pot wings

To be pedantic everything that produces electricity is a GENERATOR, and usualy comes as either a dynamo or alternator.
Now even a dynamo produces ac in the windings that is converted to dc by the brushgear, its a very complicated explanation that im sure can be googled, an alternator changes ac to dc with a rectifier using diodes which have no moving parts.
In a dynamo the brushes have to carry the full charging current and so need to be large and hard whilst alternators can be permag and vary output on revs or have a dc fed rotor which needs a lot less current needing tiny brushes.
I pdi'd one of the first GL 1000 in the UK and there were a few "teething" problems Honda said nothing about like the crown wheel/shaft spline drive


Hope that helps a bit
