Quiet Diesel generator Error Code 46

The Onan Quiet Diesel generator in our 2005 Vectra stopped working and won't start. It displays an error code 46 which the manual says is low voltage. I've checked all of the fuses (3-underneath the inspection panel) and fuses at the battery relays. The voltage across the 12-Volt input terminals checks out at full house battery voltage and I've removed the terminals and cleaned them.

I also tried connecting a 12-volt battery direct to the terminals bypassing the house batteries and had no luck. Any help is appreciated!
