Also, the voltage regulator is likely capable of 1amp max. You could be drawing more than that if the current transmitter is hooked up incorrectly. What is the spec for current draw on the oxygen sensor?

You are exactly right about the transmitters but I believe its hooked up correctly. Whats not clear in the picture is that there are 3 connectors there not two. It is hooked up as the O2 sensor directions state: one lead to 9-24v DC power, one 4-20mA output lead to the transmitter (+), and one lead that has a common ground for the transmitter and the power source. Am I right?
