1) Current sensor has a 3 pin connector with the left, when looking at it with the pins at the bottom, marked "P1" is this correspond to "+" on the Brain?
What value should I get with no current through the sensor?
2) I've connected the voltage isolator as per, http://www.mp3car.com/vbulletin/fb-s...ml#post1337788, I think, see attached image, but I'm not getting the expected result. Expected 4.6volts(940) but I'm getting 1.7(350)
EDIT: OK my "guesses" for the current sensor were correct. Have it connected to the brain and outputting around the 511(2.5v), is there any way to dampen it, so that the output doesn't jump around?
