Hi HK,

here are my results.

Ardupilot with V2 shield: I confirm your readings, but

Ardupilot with V1 shield:

From Source 2 - Purple to:
Source 1 - Purple - Good Connection
#1 - Red - Good Connection
#2 - Red - Good Connection
#3 - Red - Good Connection

From Source 2 - Cyan to:
Source 1 - Cyan - Good Connection
#1 - Yellow - Good Connection
#2 - Yellow - No Connection
#3 - Yellow - Good Connection

Strange is that on V1, 5V GPS connector has TX-RX-5V-Gnd, instead of V2 IN-OUT-5V-Gnd.
3V GPS connector has RX-TX-3V-Gnd, that match with V2 IN-OUT-3V-Gnd.

Don't know if this could be of interest, but it sounds a little strange to me.

Hope this will help a little,

chilo

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
