If I use the LEM, it adds the 2.5 volt to the mixer that has to be compensated for by the LM317. The Lem starts at 2.5 and adds or subtracts .0125 volts per amp, depending on which direction the current flows.
OK, I toasted another PFET today, I have not put the totems on the Pfets yet. Can you explain why I'm frying the PFETS, I don' think the current is whats killing them, I killed one with power supply and another on the vehicle, the Nfet survived, the 30 amp fuse did not. I plan to put the totems on tomorrow. If I can understand what's going on, it will probably explain what I've been doing wrong for a couple years.
