Can I get some of you guys to try this test with your ArduShield? I wondering if this is a soldering problem on my end or if we need to add some more wires to the shield...
You'll need your ArduShield, ArduPilot and a multi-meter where you can test continuity (Ohms). Plug your shield into your pilot and then touch one probe to the purple connection on source 2 and then touch all the other purple and red connections.
Then touch the cyan circle on source 2 and touch all the other cyan and yellow connections. Please post your results like those shown below:
From Source 2 - Purple to:
Source 1 - Purple - Good Connection
#1 - Red - No Connection
#2 - Red - No Connection
#3 - Red - No Connection
From Source 2 - Cyan to:
Source 1 - Cyan - Good Connection
#1 - Yellow - Good Connection
#2 - Yellow - No Connection
#3 - Yellow - Good Connection
