Disconnect the cable at the starter and alt. Tape them up.
If it's still ""shorting"", its just the cable itself ,cut through the insulation, or similar, on its way from back to front of car.
are all your holes through bulkheads etc nicely bushed, to stop cuts?

The way you have it connected is correct, Do as Col said... either a short in the cable somewhere or maybe where you had the lug on the starter or alternator it was touching the body of the starter/alternator.

So I've put my battery in the boot of my LC but it's shorting out somewhere, anyone know how it should be wired up? I've earthed the block to the chassis and the battery negative in the boot to the chassis, the battery postive straight to the starter and the alternator to the starter as well.. where have a gone wrong?
By shorting out do you mean it won’t crank? If so there are a few other things to look at other than those mentioned above.

Agree, sounds like there is a short somewhere in the run of cable.
Perhaps it has been a while since installing the battery cable through the car and you have performed other assembly work since and penetrated the cable insulation with a screw or pinched/squashed the insulation on the metal bodywork?

So if the lugs are touching the starter body that could cause it to short out? that might be the problem. should there be some sort of rubber washer type thing under the lugs to keep it off the starter body?

Usually its plastic surrounding the lugs but the actual body of the starter is nearby, It is possible for the lug to touch to body if the cables are not run to avoid it. Any part of the starter body is direct ground path.

Ok thanks, there's a good chance that's my problem then as i can't see anything wrong with it

It should be impossible for the circle terminal connectors to touch the starter body if you have them connected to the correct terminal which is the one on the solenoid furthermost from the starter motor.
The terminal with the longer thread at the top of the pic.

Take pics of each end, and show us how you have actually fixed the cable to the body.

I checked it out last night and you`re right, i can`t see how it would touch the body of the starter.. BUT i`m starting to think maybe the lug on the alternator might be touching the alternator body, would that cause a short as the wire from the alternator goes to the starter which is connected to the positive on the battery?
