I just used some solder that I got from the LHS. I use it for everything and never had an issue. The guy at the LHS told me to gt it, that it was "the best" solder they carried. It sure doesn't seem to be a low temp solder. I usually have to run my soldering station all the way up close to 900 degrees to get a good fast solder joint. I don't think the solder is the problem, but if it happens again Ill have to see about finding some "high temp" solder. Anyone know of any?

This instruction sheet shows a diagram of the traces on the back of the motor. The breaks in the traces marked "D" and "S" are the spots where you bridge the gap with solder to make the connection in either the "D" configuration or the "star" configuration.
I removed the solder from the D connections and bridged the S connections.
I am wondering if maybe its possible that I didn't use enough solder on the bridges and they heated up locally from the resistance and melted themselves. The weird part is that it just stopped. All 3 melted at exactly the same time. Not sure if I can swallow that, but I don't have a better explanation. I used a little extra solder this time so hopefully that fixes it if that indeed was the problem.
I'm hoping that someone around here has some experience doing this. Its the first time I tried it. I think that CHC did it once for his High Voltage project. I'm just hoping this doesn't have the same disastrous ending as his project did.:032:
