If you had a problem with the L/B previously had it been allowed to fully discharge ? If so a fairly common problem is that when the alternator was fixed the charging current would have been a lot higher than normal and frequently a charging fuse will blow. Check the connections from the S/B across to the L/B, you should find an in-line fuse close to each battery which are connected via a small box, the charging relay. Check each fuse will normally be about 20 or 30 Amps, its quite likely that one has blown, personally I would change BOTH fuses if one has blown as it would have been a race as to which fuse would blow first and the other one although intact may well be suspect as it would have only been milliseconds from blowing as well!

Oh nearly forget if a fuse has blown then charge the L/B from a mains charger BEFORE replacing the fuses, as the same will happen again otherwise !
