George :
Although it's true the TR factory ammeter is not a "shunt type", it makes
no difference. The internal wire still has a resistance, and if the shunt
is the same resistance then the ammeter will only see half the current.
I'll post my reply to Dan, which describes how to measure the resistance
and why it isn't important, on the list.
