Second extruder won't stop overheating (no replies)

I added a second extruder to my Mendel 1.5 and it won't stop heating. I am using a RAMPS 1.4 with Marlin 1.0.2-1. When I open Pronterface it registers the second extruder and shows the ambient temperature. Extruder-0 heats up properly and seems to work properly, but when I switch to the extruder-1 it start heating and just keeps going until I stop it (300c+). The odd thing is Pronterface shows the ambient temperature reading as well as the goal temperature but it doesn't show the temperature changing when it is heading up.

I have changed out the thermistor with no change, and have also tried swapping the extruders but the same thing happens.

I have attached my Configuration.h file but these are the setting I changed:

#ifndef MOTHERBOARD
  #define MOTHERBOARD BOARD_RAMPS_13_EEB
#endif
....

#define EXTRUDERS 2
....

#define TEMP_SENSOR_0 1
#define TEMP_SENSOR_1 1
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 1
....

I also tired using the Thermal Runaway Protection setting with no luck.

Any ideas would be great!
Thanks in advance.
