My Skylark is overheating and I've traced the problem from the radiator fan to the fan motor relay. The relay is good but the ground wire to the relay socket that operates the negative side of the relay coil shows 14VDC with the relay unplugged and then drops to zero VDC when the relay is plugged in. There is something that is happening on that ground wire... it would seem that the wire is not broken because it shows 14VDC until a load is applied.

Actually, I believe that you my have misunderstood my question. Please, let me try again!
I removed the relay and metered the terminals on the relay socket (not the relay) The two terminals that supply voltage to the relay's coil have 14VDC (the relay has no voltage because it is unplugged but the relay's socket has voltage that it "feeds" to the relay. I tested the socket with a good relay, test leads, and a volt-meter. The test leads allowed me to connect the relay coil to the socket and in such a way that I could also meter the voltage at the same time. The voltage is zero volts when the relay is connected to the socket and 14VDC when the relay is disconnected from the socket.
I hope this makes sense...
Do you have any thoughts?
Thanks!
