Yes.......are you sure that the battery is "in the loop" here? You can check this easily with a small digital multimeter. The DC voltage should be the same on both sides IF it is working. IF not, you can move the cable over from the one side to the other side and see if you have power. Be sure that the battery just isn't dead. Let me know what you find and we can go from there.
You may have some dirty battery cables and how do you know the battery is good? Did you have it load tested?
Just checking back in to see if you were able to resolve this issue or do you still need some additional input from me here?
