I'll try to see if I can find some code. I've been doing Arm7 C programming the last two years, so I have to dig out my old basic files. My code worked well in two Ford vehicles, and I drove them both through a full winter using the starter every cold winter morning! I built the first one on a Lab-x board from melabs, it has an LCD to show whats happening, but the output to the laptop was safer for testing because I had history to look at after I drove the car.If the initial battery voltage was about 11 vdc, the processor would refuse to try to start the engine. I typically see 12.4 to 12.8 before the starter engages, and 13.8 or so as soon as the starter is disengaged. Happy New Year!Jerry
