Is the coil drawing an unusually high current?. The field internal resistance seems to be about 1.5 ohm. Trebling total reis reduces field current to 1/3 and, altho not necessarily linear, output probably simialr. So if 2 amp running coil current 10 amp gross reduces to 3.3 and with coil current subtracted, almost no net output
If the resistance winding is unenclosed and not insulated could short a few turns with a wrap.
