After that mistake my display shows my Hot bed sitting at 149 when cold and my EXTRUDER WILL warm up but it will not display the correct heat.  My bed will not even activate because the machine thinks it's already 149 degree's.  I was hoping i could just replace a diode or resistor but i can't see anything on my motherboard that looks damaged.  I thought maybe there was a short in the mk2b heat bed, but my Thermistor on the extruder isn't operational either.  I traced the wires back to the motherboard and can't find any burnt up connections.  I'm at a loss right now and hoping i won't have to figure out how wire in a new motherboard.  If anyone has seen a problem like this or heard of anything like it please point me in the right direction.

I'm ordering some more Thermistor's and a new mk2b bed and if by some miracle replacing them works i'll write that off as an easy win.  Otherwise i'm not sure where to start to get my Thermistor's in working order again.  I'll update as soon as install the new Thermistor's and MK2b bed.
