Yes, there's probably a problem. The furnace doesn't take that much power.
Maybe if you ran it continuously all night but that doesn't seem likely.
Either you were running something else, or the battery wasn't fully charged
when you parked for the night, or the battery is shot.Since there was
obviously some charge to the battery it's not likely that your charging
circuit is dead - so I'd start with checking the battery - s.g. tests
should help diagnose any obviously dead cells. A properly configured meter
can spot overall voltage shortage (remember Voltage NOT Amps or you're
going to be buying a new meter.)
