1989 Reatta
I just picked up a 1989 Reatta last night and it seems to have a problem charging the battery. I found an added wire coming off of the alternator that is not factory. Is there a wiring diagram anywhere? Also, my dash and CRT are both non-functioning. That is next step. Thanks in advance!
