William, Wrenches Yes I do and it does require some basic electronics to make it work correctly, you will need to remove the ttemp sender and make a resistor pack to simulate the 77 degree reading otherwise it will not charge properly, for the first one I used a breadboard to set the temp for what I wanted to see then build a more solid state shrink wrap resistor. Doing this will prevent undercharge by the SMA and your customer will be happy to see the full state of charge at the batteries. OldSchool fun times
