(...) Thanks Dustin, those will help. I am inclined to agree with Philippe Hurbaine on the regulator. It is also obvious that it can take AC from the full wave rectifier near the power port.

(...) The BDX34 transistor + toroidal inductor above + LM339 comparator probably compose a switching regulator efficiently converting 13V input power to 4.5V for the outputs. Philo (18 years ago, 8-Apr-06, to lugnet.robotics, lugnet.technic)

I've taken some more detailed pictures of the circuit and the reverse side. (URL) through the manual, connections 6 and 7 are for sensors and connections 0-5 are for output (4V as labled on the cover), but you only can turn the circuit on or off. (...)

(...) Hi Dustin, I am an EE. Before I give you some advice, I need a bit more information about 9750 (I have never seen one in person): - I see a power jack: I assume this powers the electronic circuit, not the loads, right?
