Thanks Dan
Great job as usual. I believe a post from Randall Young was where I first saw
the shunt idea mentioned.
For those that might not get to Dan's website he suggested that one thing that
would improve upon the shunt idea would be;
"If someone with a VERY precise ohmmeter would measure the meter resistance,
and then measure various wire sizes for resistance, or, taking another approach,
would do a series of experiments to derive the wire gauge, It would be a great
service to those of us want to retain the ammeter, yet swap to a larger
alternator."
I don't have a precise ohmmeter, but hopefully someone on the list does and can
fill in the blanks for the rest of us.
Thanks again to Dan and Randall

Listers,
Someone on this list suggested using a shunt to increase the range of ammeters
to allow the use of higher amperage alternators without having to lose the
ammeter function. Unfortunately, I missed the original post (you won't believe
how busy I've been of late - especially for an old retired coot), so I don't
have the individual's name.
A couple of people have contacted me off list to ask about it, so I thought I
would put together one of my long winded dissertations on the subject, and
ammeters in general, using some material I had already put together, and post
it on the web.
Using a shunt is an excellent idea, but as usual, there are a couple of
"gotchas" to be aware of. The write-up can be found at:
