There's actually an easy way around that, just add a shunt across the ammeter to
carry part of the current. It's fairly easy to find the right length of wire to
add, such that the ammeter reads 1/2 of what it did before; allowing you to keep
that vintage Lucas ammeter along with your alternator.
I've not had any trouble with mine since doing that almost 20 years ago on my
TR3A.
