Randall and Dan,
As a summary for me and the list too....
The ammeter shunt, and Randall's many years of TR3 operation with an
alternator, have alleviated my concerns about wiring the alternator up in a
manner which will enable me to keep full ammeter function, albeit at
readings half (or whatever percentage I choose) of what is actually flowing
through the system.
The way I see it, Randall's "easy way" method to come up with a 50% reading
on the ammeter is to run a constant amperage load, such as the headlights.
Using a trial and error method, with several different wires, or a series of
strands to varying the load across the ammeter terminals, until the ammeter
in the car show a reading 50% of what it shows without the shunt. A very
eloquent solution!
Randall, this is simple enough for even this Mechanical Engineer. Now that
I have a full understanding of how I would install an alternator in my TR3A,
I am sure that the generator will be able to keep up with the new electric
fan and the alternator will not be needed. ;-)
Thank you,
