Sorry to send this again but I cut one leg off and the whole thing stopped working! me thinks I cocked up!
 
The thing I cu one leg from had 3 legs, do not know what it is, I have soldered it ant all seems well but LED still on.
 
Any other suggestions anyone?

Hi Steve,
There are two blue round flat things one of which has VG7K or maybe VO7K written on it and has Fuse written on the PCB.
There is also a Blue(ish) box with OKAYA PA224 0.22yF  K written on it, I assume this is some sort of capacitor.
 
On the other end of the PCB there is another blue round flat thing with a white wire near it going to the coil.
There is a small black "D" shape item with 3 legs (similar in shape to the DS1820 temperature sensors) near with MCR 100-B written on it I cannot see a silver band on the end though.
 
Sorry but I am still not sure what item to cut, any suggestions?
 
Thanks again.
 
B.

Brian,
 
Usually there will be two capacitors, these are usually blue or orange. Next to the small one there will be a diode, this is a black component with a silver band at one end. Simply snip the lead at one end of the diode. Also likely to be near to the flying lead to the relay.
 
HTH
 
Steve.
