Chasing a Current Leak

I've done a bit of Googling and still don't know what those black plastic blocks are on the back of the original LR unit. May be my go to guru @Kwakerman can tell me?Anyway, I've came to the conclusion that my spark must have been a short between the B+ terminal and the adjacent alternator bolt, via the metal heat shield. (Shouldn't have reconnected the battery so soon) To be on the safe side, I've added a plastic insulating stopper on the end of the B post

And carefully refitted the heat shield.
Once the battery is fully charged, I'll start her up and see what voltage I'm getting at the battery.
 
Battery fully charged and I’m getting 14.04v across the battery terminals.
Next test will be starting when the Landy hasn’t been ran for a week.
 
The black rectangles connected to B+ etc on your old alternator are almost certainly interference suppression capacitors. Your new alternator will run perfectly well without them but you may want to fit them if you get interference (typically a whining noise that varies with engine speed) on your radio. The interference is usually worst on medium and long wave as FM is less susceptible to the sort of interference that alternators can produce.

Cheers mate. That had occurred to me as a possibility, but I was only guessing
 
Yep, agree they are suppressor capacitors, shouldn't really need them these days I think they were more of a nessesity back in the day when people used AM radios

Yes, suppressors makes sense. The battery seems to be staying spritely, so hopefully it hasn't suffered any long term damage and will live on for a good few years yet. :)
As I said above, the acid test will be when it has stood for a week. Most times it's used daily.
