If you measure 6.4 on each then you have 12.8 and are fully charged.
Do you have a couple of other 12 volt batteries nearby? If so, measure them as well.
Then you need to make a couple of measurements in the front run area. There should be a large circuit board in an outside compartment just below the driver.
We need to know if the full voltage is getting there. If you can take a picture of the battery compartment and the front run compartment it would help.
