Ignition switch loses power when turned on

I have a Craftsman T210, model 13boa1zs093. I need the wiring schematic for it. The R/W battery wire has power with key off, but drops to 0 volts in all other key positions. I disconnected the ignition switch and jumped B+ to it. With the key on, power remained, so I jumped all other circuits. Only circuit A1 (white wire) caused loss of B+ at ignition switch. I disconnected the main connector for the stator, rectifier, and some relay but it had no effect. Disconnecting the headlights allowed 1 volt B+. Can anyone provide me with the actual wiring diagram/schematic for this model?
