When you find one with a broken fan, you'll know it. They sound like all kinds of junk is rattling around inside.
Most Singer wiring systems use the 18-2 SPT2 wire. Cord block sets like the Japanese machines use usually use the 18-2 SPT1 wire. Non Singer motors can have either size insulation. I just replace the cord with the same size when I rewire them.
The only difference between the SPT1 and SPT2 is the SPT2 has thicker insulation. The actual wire inside is the same.
Find a piece of cord that is marked and strip some insulation from it. 18 gauge wire is very consistent in size. That is all I use on my rewires. No 20, no 16, just 18 ga wire.
