Terry, I think you are off base on the fuse rating. Think of each
fuse as a link of chain. Whether you have one link rated at, say 30 lb.,
or 3, the chain will only support 30 lb. The 3 fuses should be in
parallel to get higher current protection.
There are a number of problems with using fuses in this circuit.
Fuses are generally designed to blow at a particular current at a temperature
much lower than will be found near the alternator of a roadster, so they
will generally blow at a lower current than they are rated.
Fuse holder clip to fuse connections don't like water and heat which can
cause corrosion and further heat buildup at the end of the fuse, also
causing it to blow out at a current lower than the rating. This can
also cause intermittent connections.
Increasing the available current to the existing wiring (by adding a
fuse rated at higher than 30~35 A. can cause the alternator wiring to
overheat and melt, or your ammeter to burn up.
I would suggest adding a fuse link at the alternator connection to the
harness wire and not try to get the extra power out of the alternator
using the stock wiring harness. Use a high quality crimper to install
the fuse link because most cheap crimpers don't make a gas tight connection
and allow corrosion and heating in the connections.
Peace,
Pat
