What do you mean by no shunt.. Which component specificially, the .25 Ohm "R2", or the 10 Ohm "R3" (the actual heating "resisitive/inductive element"). And, if it is indeed R2 that you "skipped", did you replace it with a wire so there is still a connection between the neg of the batt and the MOSFET?

Do you have access to a Scope, by chance, and/or a digital camera?

Sorry if the questions sound overly simple, it is an old habit not to make assumptions, cause they are often "wrong"
Hi Jibbguy I think I've made a silly mistake I hooked the mosfet wrongly; misunderstood the schematic G and S shorted them . Only S should be to negative and G to Pot. I became aware today. Tommorow I test it.
