mm i'm not sure if it died whilest it was driving the FET. it all happened rather quickly. however; yes it was connected to said fet. to test if the temperature sensor will work safely with the big battery shall i connect one up w/out the fet (as i don't have one of those anymore
) and put my multimeter between ground (-ve battery terminal) and the /out... and see if the voltage goes to zero once the temperature trip point is reached?
and if it can do that without smoking... well theoretically it should easily drive a fet shouldn't it? (like in the second diagram that i attached earlier)... which could only mean that i somehow bollocksed the first prototype up somehow...?
thanks so much for all yous guys and gals help btw... without it i'd be down to my last sensor. come to aus and i'll buy you a beer
