I'll reterm all my twisted pairs in case a crimp broke, on quick inspection
all was clean, tight and intact. I completely discon the sensing wires and reset back to default, reset amp-hour capacity, and still same. As far as I know there is no user recalibration for voltage. I have the manual. This thing is supposed to read voltage right out of the box when attached to a good sensing point (the positive bus bar) and amps when run thru the shunt. User setpoints for CEF, amp hour capacity, charge floor are just to provide you with accurate charging perameters and time to charge info according to manual. I'll reterminate the sensing wire though, good call, there's no reason why that wire coming right out of the unit to the pos house bus would read off unless it was faulty. Maybe Cruising equip (xantrex) has an option. thanks for letting me vent. I love this forum.
