Test Results:
Slightly faster bipolar: at 16 volts and running at 12 scale mph amperage is between 0.3 and 0.4
Slightly slower bipolar (suspect one): at 16 volts running at 12 scale mph amperage is around 0.7
Thus, it appears something is amiss in the slower one...although after my DCS battery assumptions were wrong, I suppose I need to test a 3rd bipolar to see what it comes in at...because it could be the faster one is not normal...but I doubt it because the slower one continues to exhibit an ever so slight hitch or stutter at slow speeds...barely visible to the naked eye but its there.
FWIW: the suspect bipolar is coming up in conventional upon powering up Z-4000, but then I can address it via DCS remote and "start up."
Should I pull the motors out of the gear box...not an easy job but I can do it if the consensus is to do so...but what should I be checking for? Or, could this be faulty electronics?
