Thank you Lowell & Dan... you're absolutely right of course, & thanks for correcting me. That'll teach me to use my keyboard before engaging my brain! The situation still seems rather odd however - it would seem to be very unusual that the wire size & length would be so critical. The wire size & length would usually be selected as to not create any appreciable voltage drop to a device like a motor. I guess that IVO may be limiting the voltage to something less than battery voltage with this wire. It's interesting.
