I think that's it.

The voltage the DDEC sees is different than seen by dash gauge or even my xantrex readout. It alerted me both with its low value and jumping around that my block was badly grounded; I get much better voltage consistency (but still in the low 13s) since I ran a heavy ground wire to a block bolt.
Don, I guess I am kinda slow today. You have that Silver Leaf stuff in your coach, right?
