Hello Xilofono, I'm sorry entering in this discussion but my problem is similar to Carloscastro's one and also a little bit different: my wire colors are (RED on the left, BLACK in the middle and YELLOW on the right of Motherboard) [ ].
In this case, what color wire could I plug in positive (+) pole power cable?
I'm sorry to disturb this discussion but I'm not able to find anything, it is since Friday that I am trying. This solution (to give power at the probe) is the first suggestion positive I've read.
Best regards.
