Thermistor showing 2000

Small update
I decided to erase the firmware on this board and get everything to exactly the same on this board as my other one.Still getting this. Heater 1 and 3 are the only ones with thermistors plugged into them at the moment but still shows 2000. Heater 3 is coming from the Duex5 which is a brand new board.

Looks like one of the older revisions, can you tell which one?
And measure the resistance from the left thermistor pin to ground (in the same orientation as in your previous photos)

Don't need the picture, the value is enough, 10.4 ohms? no kilo or other prefixes?
And the revision of the board? Should be part of the silkscreen near by the red probe. says something like pcb revision 1.nn(x)?
-
Oh sorry didn't notice that it cut the bottom of the meter off showing the setting. It was 10.4 kohm
Board version is 1.01 -

@bearer Oh you know what.. you just sparked a memory from about 3 years ago. I had to replace the F1 fuse on this board before because of this issue. I checked it with my multi-meter and sure enough it is blown. I bought 5 of those last time... now I wonder where I put those.. haha
-
tape the bag to board when you find them?
-
Holy crap I found them.. And my wife thinks I keep too much junk from my 3D printer builds.. haha

Awesome!
(btw if your wife really thought you kept too much junk I don't think you would have found them;)
