Hello,
What does the battery voltage at the battery cables read?
Expert:  Virtual Wrench replied 1 year ago.
Attach the meter cables to each battery cable and get me the DC voltage reading

Hi,
Do you still need help with this?
From what i can tell the battery is way to low. It should have had higher volt readings that you posted earlier.
