What Richard said.  Let's talk about a hard restart, what all was turned off/disconnected?.  Do you have any Solar and if so was it disconnected?  Silverleaf can be fickle, I disconnect any shore power and turn off the house and chassis battery switches BUT there may be a wire directly connected to a battery that doesn't go through the switch.  Sometimes it takes several cycles of turning power off before Silverleaf fixes itself.  Occasionally I have Silverleaf displaying zero or a low battery voltage and after trying to reset it a couple of times I ignore it and eventually it corrects itself.

If you have done the above, it's time to call Newell tech support.  They are the Gurus Guru.
