The end cap assembly comprises an end cap supporting two motor terminals and two brush assemblies. A chip capacitor is connected between the motor terminals. The positive motor terminal is connected to the positive brush assembly by a choke and the negative motor terminal is connected to the negative brush assembly by a PTC. The negative motor terminal is also connected to the motor housing by an earth strap which is nipped between the end cap and the motor housing.
