Completely new to motorhoming!! I have a 1997 santra. We were running the generator last night and it ran out of gas in the night. Woke this morning and cannot shut the coach batteries off with the switch. The LED stays on constantly. My steps won’t retract and the generator won’t even try to start with the switch. I can hear a click when trying to start generator but won’t activate. My water runs when flushing and using the sink. I have read it’s possibly a solenoid???
