Assume motor is 6 lead. Leads are numbered 1-2, 3-4, 5-6. Each pair for a phase.
Assume Delta connection L1=6+1, L2=2+3, L3=4+5
Assume Wye connection L1=1, L2=3, L3=5, jumper=2+4+6
Switch Delta or Wye
Common A = 2, Delta = 3, Wye = jumper
Common B = 4, Delta = 5, Wye = jumper
Common C = 6, Delta = 1, Wye = jumper
Drum switch Delta, OFF, Wye
Common A = L1, Delta = 1, Wye = 1
Common B = L2, Delta = 3, Wye = 3
Common C = L3, Delta = 5, Wye = 5
Common D = 2, Delta = 3, Wye = jumper
Common E = 4, Delta = 5, Wye = jumper
Common F = 6, Delta = 1, Wye = jumper
