T1 and T2 not reading any input temperature on RAMPS 1.4

I have a Prusa i3 with RAMPS 1.4 electronics. The printer was second hand, without a heat bed. Currently, I am installing one.

The thermistor is functional, if installed in T0 slot, the reading is seemingly correct. However, both T1 and T2 are not reading any temperature, as confirmed by giving the M105 command.

What can be the problem?

You might have to change the type of motherboard from "EFF" to "EFB" in config.h?

// The following define selects which electronics board you have.
// Please choose the name from boards.h that matches your setup
#ifndef MOTHERBOARD
  #define MOTHERBOARD BOARD_RAMPS_13_EFB
#endif

The problem is that I do not have the original files (did not flash the board myself). I want to read the settings that is in the arduino, but do not know how to.

You can use pronterface on your PC, make a USB connection and take a screenshot of the "bootscreen" on the right. It contains a lot of useful information to start your own Marlin adaption.
Having another pair of Mega/Ramps boards would come handy. ( also for spares and the next project winking smiley
