Ok, I am getting a large voltage drop from the ARII to the gameboard. Below are my readings.
ARII - Back of J7 = +5.31
EMI Shield - Back of Edge Connector = 5.17
EMI Shield - Traces = +5.14
EMI Shield - Back of Gameboard Edge Connector = +5.06
Gameboard - Traces = +5.00
Yes, it still has the EMI shield. I am guessing the first step is to replace the edge connectors which connect to the EMI shield. I have also read that the EMI shield is not needed. Should this also be removed? Almost 2/10 of a volt is lost in the EMI shield alone. What is the purpose of this board (besides EMI protection) and why have people suggested removing it?
