Hi, I've just bought a 1202 from ebay only to find that is has suffered some water damage internally at some point in its life - how it can be described as in 'good working order' is a bit of a mystery to me but there you go.

The main area of concern appears to be the relay, arms, cap and diode assembly contained in the clear plastic box. This has some evaporated rusty water residue contaminating the relay contacts. I have opened the plastic box and need to give the parts a good clean but will need a detailed drawing to ensure that I get the hair spring and arms put back in the correct place and that the relay contacts make and break correctly.

Unfortunately the service manual from this site doesn't show this in sufficient detail for me to do this - is there a better drawing I  could refer to?

Also whilst I've 'got the bonnet up' is there a service kit available for any other components and service items including the drive belt that are worth replacing/upgrading available?

 
This is my first post so any help and advice would be very much appreciated.

Best regards,

Matt
