I recently purchased a 1951 John Deere Model A tractor. I used to own a "B" model. That model featured a 6 volt electrical system. Checking the specs on the Model A, it says it's a six volt system as well. However, when I checked the battery compartment, it had two 6 volt batteries ganged together in SERIES, which means it's providing 12 volts to the tractor. So, I'm a bit confused - is the system really a 6 volt system or not?? Did the previous owner screw up and connect the batteries in series instead of parallel?
