Hello Bill and everyone,
To clarify a "heat of the moment comment by me" Mastervolt did get back to me, their customer service is very good after the right person was contacted in Florida. I sent the charger to them and they determined that it was faulty and was not in their opinion repairable. They offered me my choice of Mastervolt chargers at dealer cost. I am considering that or the Iota. The tech at Mastervolt pointed out that a 30 amp charger was very small for a 2 8D battery bank.
Thank you again for the input
