All I can say is that you don't have to exceed it by very much, before a
rebuilt generator will only last a few months. Thrown solder is another
symptom of overload. BTDT

True enough. In effect, the two-bobbin design means that the full current
capacity of the generator cannot be used to fully charge the battery, as the
voltage set point will sag under heavy current output.

Especially when it comes to automotive engineering ! I do wonder tho, how
much more expensive the 3-bobbin regulator was ? It was readily available,
and IMO Triumph well understood the difference. My "6 cylinder Herald" uses
a 3-bobbin, while the Herald had the same 2-bobbin as the TR2-4.
