Guage won’t take Manual fuel input

The other day when adding fuel I went to manually enter it and it did not store it. I did it numerous times and nothing. The gauge won’t take it. Motors and rest of system work fine. No alarms or anything. Any suggestions?

Perhaps low voltage to the network? Many years ago similar problems were caused by that. Try putting the batteries on charge and doing it again.

If that doesnt work, only other suggestion is to run an auto select for network data sources just in case its lost comms with the duel data sources.... long shot....

Thanks. I’ll try that
