Fidjet13

I'm having issues since i swapped the motor most of which are wiring issues. My main issue at this point is that the battery isn"t charging. I plan on replacing the alternator in a week or so but was wondering if that as well is an issue from wiring or not. Simply seeking guidance and assistance and any other issues i may not yet be aware of yet a heads up wiould be awesome.
