I am trying to get the built in TEC to work on a TO3 red diode, I used sam's laser faq to correctly identify the pinout. When applying 3v and 100mA of current in the correct direction of the TEC I get the resistance of the themistor to rise like it says it should in Sam's laser faq. But this causes the diode to heat up, and if I reverse polarity on the the TEC it does the same thing, except it causes the resistance of the thermistor to decrease. Any help?
