Thanks Dave w.The sense resister jumpers and memcal mod are the 2 things I did do long ago.it's been sitting in a box waiting for this conversion. But since doing those 2 mods I read the memcal mod was not needed.I also unsoldered the factory chip from the memcal and soldered in a socket and then a zif.I don't have an extensive background in electronics per say unless rc cars qualified.I'd guess not.:rolleye
