do you need to use your tuner to ck voltage or can you use a DMM.
What exactly are you testing "in your harness"?

if your getting neg. voltageout of a dmm then your leads are backwards.

yea like he said with a DMM you can just swap the leads and it will read the same thing just Neg. Now if your tuner is showing it I would start to wonder if you lost a diode in the alt.
Which "regular" harness?

oh, K-then stock regular wiring harness. That narrows it down as well is if I gave you directions to that road, you know the ones with the lines on it, and a stop sign too!
