Hello, XB12scg quit charging. Checked stator and it is O.K. have new regulator with new 77 connector included.

My question is, both wires from the regulator to the 77 are black. From the 77 to the battery is red/black. How do I know which wire to hook the red wire too?

Also, I don't have the special crimp tool that the instructions call for, can I crimp and solder using a regular 10ga crimping tool?

Thanks
