Tom and All following,
After doing a hard reset on my ME2012 Inverter/Charger, I applied power but it's not charging my batt bank (@12.3 VDC). I called Magnum Tech Support, and after some additional discussion, the technician told me the unit is not repairable (almost 20 years old) as it's operated almost double it's life expectancy.
I have ordered a new unit from Inverter Supply and upgraded to a pure sine wave inverter (MS2012) as recommended by the Magnum tech representative. The new unit should be delivered next week. It has the same physical configuration, so replacement should be an easy straight forward process.
I'll provide additional info if anything else of value comes up.
