Some follow up info on the failed connection.
I got a chance to go flying this morning (Sat, 10.24) for the first time since the Salem, OR, meet. I noticed that the motor seemed to be losing RPM when loaded up in verticals, etc. After some checking , it appears that the terminal that was re-soldered had apparently gotten hot enough to anneal the spring leaves in the connector. It only takes about 1/3 the force to pull this one apart compared to the others. In addition, the electrical tape I used to bundle the wires had a hole melted in it at that connector.
If you have an occurrence like this check to make sure the connector is mating with the same force as the others, and pay some attention to make sure the connector isn't running hot. Turns out the electrical tape was a good over temp indicator.
This points up that I do not know which was the cause and which the effect. The connector may have been marginal which could have caused the solder failure, or the other way around. The re-soldered joint appears to be OK, so bad solder could be the initial cause.
It will be interesting to see if the power consumption goes down after this is fixed.
