The two coil regulators used on all "T" types only regulates voltage. It
can not control current as does the three coil units. The voltage
setting should be around 15.5VDC. That is why a bad battery can burn out
a generator. It continues to try to bring the voltage up to the
regulation point and supplies too much current for it own good. The
TA/TB and early TCs had a three brush generator which could control the
output current.
