It dawned on me that I was being a bit thick - I spotted the numbers on connectors both ends - matched the wires up using a tester to make sure all was OK. Replaced the carbons - put it all back together again - motor still not working. Bought a replacement motor - installed - switched on - loud...
Just changed the carbons on the motor of my Siemens WXLM166AGB - putting it back together noticed a wire had become detached from the clip that goes into the back of the motor - eased the motor out again - 3 more fell out....
7 wires in all - all orange - no idea which one is which - HELP...
