[Mgs] alternator on 71 mgb

[PaulHunt73]

If the light goes off when the plug is removed from the alternator (ignition 
on) then the alternator is at fault.  With the engine running at about 
2000rpm measure the voltage on the brown or white at the fusebox.  If it 
only reads 12v then the alternator isn't charging.  If it reads about 14v 
then it's charging, but there is still a problem with it.  The difference is 
that if it's charging you can still use it while you source the best deal 
for a replacement or repair.
