[Healeys] Tachometer problems

First make sure that the tachometer body is grounded.

Hi everyone,
 
I have a positive earth BJ8 that I am putting back together.  I spent  the 
day getting the engine into basic tune when I noticed that the tach wasn't  
working.  I checked the wiring diagram again to assure that everything was  
connected correctly, from the tach to the ignition switch to the distributor
and  
coil.  Everything seems right.  I do remember hearing about the  direction
of 
the loop the white wire makes as it passes through the white nylon  clip on
the 
back of the tach to the ignition switch; depending on whether  the ground
was 
positive or negative.  I took that out and reversed its  direction and still

no function.  Any ideas or knowledge as to why tachs  don't work??
 
TIA,
 
Bill Schumann
