Paul,
For some reason I thought you had a TR3...unless yours is not stock, you
should have a mechanical tachometer. The cable that drives the tach is
connected to the dist pedestal.

  Thanks for your reply!
  I've heard that the tach may require different wiring.

  It is not difficult for the change over:
  1. connect your ground from the fire wall to negative side of the
battery...make sure ground terminal has good contact with the firewall
(original) or (ground strap from battery to the engine non-original) if you
prefer
  2. positive side of battery terminal to solenoid
  3. reverse wire terminals to amp gauge from schematic
  I never hooked up an alternator to my TR3A so I let some of the other
listers chime in.
  Sorry you had to go through those initial pains...but it will be worth it.
  My finished TR3A will be done in March or April.
  Just in time for great weather in Las Vegas.
  Ibsen
