I replaced the brushes in a YDK 04/07 motor but there is an awful lot of arcing when I switch it back on.
On doing some research people suggest cleaning the armature with a bit of emery cloth.
There is only a limited amount of space to stick your finger in whilst turning the armature so was wondering if there is any better way to do it?
I can't see an obvious way to dismantle the motor to do it?
Any help greatly received
