Today I have been able to find some free time to do some basic current testing using my bench power supply, and USB Oscilloscope.

Using the oscilloscope across the current sence resistor I get the following results.

Bipolar Parallel
DIP Switches 1-2
ON/ON: 0.469v avg / 0.33ohm = 1.421a.
ON/OFF: 0.313v avg / 0.33ohm = 0.948a.
OFF/ON: 0.234v avg / 0.33ohm = 0.709a.
OFF/OFF: 0.078v avg / 0.33ohm = 0.236a.

That looks about right... i assume by average you mean RMS, so the peak current will be around 2A. Can you post waveforms as discussed?
