Falstaff, following up on my earlier reply asking about whether or not your truck previously had air suspension (aka SLS) here is a link to a post of mine from last fall on the topic. Be sure to click on the link for the Land Rover TIB on the topic.

Feeling good about the alternator, producing 13.8 nicely.

But, good grief! Now my obd port has "fallen in".
So now a side trip of pulling scrivets and trying to dig that back out.

 

OBD port? When are you ever going to need that on a Land Rover? LOL

 

13.8 volts, is nearly bare minim voltage for your computers. Was that tested with a/c head lights and radio on?
