Air-Con Problems

[bmh.01]

Everytime I turn the AC on it'll blow fuse F3. Can't really find any information on the relay side of it so I can test through so i'm after any ideas anyone may have?

Had a thought, would loosing one of the engine earths possibly cause problems like this? Its possible i've broken one when I was changing the cambelt by lifting/lowering the engine and not remembering them.

Yes fix the earth.

Earths are fine, and it was working fine when I left work then blew the fuse as i went up the road. Current theory is i've disturbed the feed to the clutch when i did the cam/auxbelt so it moves around and shorts out. Going to check on that one now.

Found it. When my dad put the alternator back on he managed to crush the ac compressor clutch wire so it was shorting on the block, never checked it or even though of it really.

Oh well a repair later and its working like a champion.
