Clean as can be

Clean the Thumb Wheel

You can take the thumb wheel off the encoder, but if your careful a bit of spray and a rag will get it clean. DO NOT get the electronics wet.
Snap On MT2500 Broken Wire

First Fatality

In messing with the Yes/No switch I broke a wire off. It's not a problem for me to fix but be careful in bending the wires as they are somewhat brittle. Also note that if you do damage the connector it's just an IC socket cut into pieces. If you break a pin off look for machined pin style of IC socket and cut it into apart. You might be able to find the just an inline socket/plug like it if you check Mouser or Digikey electronics. Also carefully use the needle nose pliers to straighten pins as they were likely bent when you pulled it out of the circuit board.
Snap On MT2500 Soldering

Soldering the Wire

If you break a wire get a small soldering iron out and heat up the connector and see if you can pull out the broken part of the wire. Heating it and banging it upside down might do it (watch out for hot solder). After soldered be careful. Originally their was a blob of hot glue or silicone on the contacts, if you have it but some on to cover the conections and help keep the wire from breaking due to motion.
