Battery will not charge

Electrical PDF
Here's a link to Electrical diagram... I'm rusty at reading schematics so I figured I'd post it up for you to look at as well.
http://www.landy.ee/manuals/electricity/Disco_Elec.Troubleshooting%20Manual%20-%20LRL0077ENG%20(1997).pdf
I'd recommend downloading it to your computer and opening with adobe reader. You can hit Ctl + F to find key words and go to a diagram with that word on the page. If you have a mouse wheel... you can click the wheel and hold to move around. You'll have to zoom to read most of it... hold Ctl and mouse wheel to zoom... or Ctl + for in and Ctl - for out.
Check resistance from the alternator enclosure to the chassis... or to negative battery post. You should get some resistance but it shouldn't be infinite. I know... it really is a stretch as it is grounded through the mounting bolts... but it's an easy test.
I'll keep looking but I am very rusty... much like most rovers... Good Luck.

I would go back to the 150A mega fuse (FL1). I've burned that out a couple of times for various reasons, and each time it has exhibited different symptoms. However, the only consistent symptom was that the battery didn't charge.
A new fuse is only about four dollars. Get a couple of them in case there's a short that caused it to blow.

Thanks Daedix. I disconnected the battery completely and hooked an ohm meter between the large wire at the alternator and the main fuse connection. i tied them both along with the positive battery terminal. All had almost no resistance to the wire at the alternator.

i tested the fuse and there is no resistance between the two sides. Please see the picture. Please keep the ideas coming.

Thanks! I have checked all the ground points a couple of times. No joy.... I have also tried connecting a wire directly between be alternater mounting point and the negative battery post. The Disco can sit for several weeks without the battery going low so the battery or "leakage" doesn't seem to be the problem. The issue is no charging. The alternator has been rebuilt and another alternator was installed previously. Both tested fine on the bench.
There is a clicking sound from the passenger footwell. It is coming from the box attached to the right side of what seems to be the ECU. It is pictured below.
Please provide any other ideas on what I can check. Thanks!!
