Ammeters

[John Clark <clarkjc@runbox.com>]

Interested parties,

It's possible to use a 30 amp ammeter with modern amenities, like air 
conditioning, by adding a power resistor in parallel with the ammeter.  The 
resistor would allow some of the current to bypass the ammeter.  The 
ammeter would then display a fraction of the actual current, based on the 
value of the power resistor chosen.
