[Mgs] mga 1500 with early 5 main mgb engine

[Paul Hunt]

It can be surprising how often you can be absolutely positive about 
something, then find it wasn't as you expected.  Nothing like proving it.

There will be no harm swapping the pickup connections at the tach, and 
it's worth trying as someone may have swapped them internally for some 
reason.

Swapping the 12v and earth is a little more tricky.  With electronics 
reverse connection can sometimes blow the semi-conductors, so it's a risk.
