Which Side of a Battery is Positive? A cell or battery is drawn with a long line and a shorter line. The long line is the positive side (plus is longer). The short line is the negative side (minus is shorter).
A reading of only 1V on the battery bank lends to the issue that your batteries are not being charged. And that could mean the charger is at fault or you still have a bad battery. When the charger is charging the batteries-use your meter and check the voltage at the + and-terminals. Let me know what you find. P.S. you can check the continuity of the fuse if your meter has a continuity checker. (or when the cart is powered on-put one probe on one side of the fuse, and the other probe on the remaining side. If your meter has a continuity check-it will have this symbol: When you touch the leads together-it will beep.
