But shorted? ..thermistor is lower resistance for higher temperature. ..is it shorted ?

Ive checked the board and i dont see any shorts. but t0 is putting out around 0,15v where as t1 and t2 are putting out 5v. Could it be a setting in the marlin firmware ?

Don't have my fw im front of me..but in configuration.h there is a thermistor type constant...now just what thermistor you were supplied and how that relates to any of the marlin presets...well who knows..its not like you would be told eh

I think I was supplied the honey well one but I'm not 100% sure and I did set my thermistor to that but still nothing

A thought..try it on T1 rather than T0...and switch to extruder 2..if it works there then its the ramps board. . ( if ramps not sanguinio)..schematics are available....
