Hi fellow FOTers',
Just been given by my friend and mentor (Chris Swingler) his 10,000 RPM
Smiths tach he ran in his Spitfire back in the seventies. I am privileged!
The tach has no markings other than it is Smiths from UK and four cylinder.
I do not have a hook-up diagram, however, more importantly because of the
period it is POSITIVE earth. As an old sparky I know what that means and
what to do. However, I would much prefer if it were at all possible to
reverse the polarity 'cos you can never fully rely upon the other fellow
understanding the significance or difference for that matter and we will run
negative earth.
Can any one help with this, otherwise it is into the old plastic tube etc
etc.
Regards to all, and yes we are progressing sloooooowly, pre-fitting stuff
like manifolds and stuff - getting ready to paint - and so on. One day I
will put it all up for you to see.
