OK. Changed the capacitor but now I cant get the motor to run at all
!!!!

Just to explain how its connected. From the switch/timer theres one
wire straight to the motor, and two to the capacitor. Then two run from
the capacitor to the motor.

The sole wire is live (I checked). What should be live into/out of the
capacitor. Why two wires in and out?

Should the motor run with just the one live? What about earth/ground?

Can someone explain whats what?

(BTW. Think I knackered the timer now though - shorted it and blew the
fuses etc.).
