Things are a little clearer now.......

So, and correct me if Im wrong.,....... Ineed a .1 microF ceramic capacitor.

If I solder one between the two motor leads/contacts, and one between each of the motor leads/contacts and the body of the motor...... then Im good to go?

One more question.......the motors Ihave have a kind of tight fitting metal sleeve around the body.

Has this any particular function other than keeping crap out of the motor?

Should I solder the capacitors to the sleeve or the actual motor casing?
