dodgy capacitor and needs a gear box oil change.
you only need the grey and black wires, black is live, grey is neutral, the 2 small wires go through a temp cutoff on the motor.
my drum just fell off, so had to weld it on to the shaft (very rusty). after a complete stripdown, grease, and oil change -works fine, i need a capacitor to be perfect .
