Hi Bruce,
I note that you thinking of purchasing a 175-amp alternator. There is one more
calculation you should look at: you should look at the charge rate curve of
comparable alternators.
I was going to have a 175-amp Prestolite. I went to J.Middleton, in City Rd,
Manchester, (Very experienced people and the best prices in the UK incidently).
They advised me to buy the 100-amp one, asa the charge rate to revs, were so
much better. It means that I can obtain the "almost" maximum charge at a much
lower engine revs; this means that on a boat, where the engine is not running
at high revs when cruising the canals, I am obtaining a better charge rate, so
the batteries are actually charged MORE QUICKLY than the larger output
alyernator. This should be considered before purchase.
Just something that you may not have known and could give you better results.
Cheers, ~Allan~
