Thanks for all the input guys. TO prevent oscillation I'd definitely have to work some hysteresis into this. Are there MOSFETS that can handle 40A continuous current? I may need to go w/ some type of IC also to do this but it's just something I wanted to toy with. I never will be good enough to probably notice a minor IR reduction but it's just something fun to play with and expand my knowledge I suppose. I'd certainly be interested in your schematics Howard
Thanks
Dave
