You probably can't, it's normally one lug on the whole stator with a coil on it. The coil is likely to be encapsulated also. It is possible to break open the encapsulation (with care) and you'll find a bobbin in there with the faulty windings on it. The bobin can be removed and the coil rewound, refitted and re-encapsulated. Suitable winding wire can be purchased from the Scientific Wire Company, Essex, Tel No. 01371 238013
To make this clear, this is a seriously determined effort not to have to pay for a replacement stator and if you fek it up your stator will be scrap.... but I have successfully done this. Bear in mind though that it'll probably be scrap anyway if the high speed charge coil is U/S.
However, I don't know your motor, you may be lucky and have separate coils, in which case you can likely replace or rewind the appropriate coil. Good luck.
