This is a small bearing 1296 engine that is now equipped with a Lucas
Alternator. I have long suspected that the smaller pulley that was designed
for use with the original generator is spinning the alternator slower than it
wants and therefore not putting out the kind of charge that it normally
would.
Joe, I am having a little trouble understanding the bit about the larger
pulley. If you put a larger pully on the alternator, it will spin slower not
faster. for example, if you take an electric motor operating at 1800 rpm with
a 4 inch pulley and drive a fan that has a 2 inch pulley, the fan will be
operating at 3600 rpm.
