i always get +/-12 vdc at this point, and i am sure the wier is either 2 12,s or 2 15's
not one of each.
a far as plus and minus goes on the 2 twelve volt supplies, you just wire one output reverse polarity, this is normal, so don't worry.
any competent electrnic tech can figure it out for you.......
along with the sense lines.
