1992 V8 automatic land rover discovery won't start off the key. on 1992 Land Rover Range Rover

The ignition switch tests ok. The starter motor is ok as when I by-pass it it cranks over. There is no power going to the starter motor. Is there any other common problems with this vehicle that I should check?
Where is the inhibutor switch located? And is there any other fuse boxes in the vehicle other than the one under the steering wheel?
Cheers Tom
