Intermittant no AC?

[bilton_d]

strang one but every now and again i have no AC butwhen i check it i am not getting the pulse feed at the compressor.
The main AC relay seems very hot but not sure if it suppossed to be.

Any Ideas?

Just changed the Air Con relay but nothing, 40Amp fuse beside the battery and the 15Amp fuse next to the steering column are both OK.

Anyone have a wiring diagram to see where the grey lead to the condessor goes?

If i put a direct feed from the battery to the condensor it kicks in.
