Tachometer kills the engine

[K10-Kansas]

When I connect my tachometer wire to my tach and distributor, my engine dies. If I connect the tach to the dizzy it won't start.I have the 2 male blade tachometer that comes stock in the stock cluster. My HEI came preinstalled on my Blueprint engine.

1. My multimeter shows continuity from the cab terminal end of the tach wire to the the engine bay terminal of the tach wire showing the wire is not interrupted.
2. My 12v wire to my tach shows 12v.
3. My coil blade on the tach shows O.L. when trying testing to any part of the metal housing, mounting post etc. on the tach and gauge cluster proving that the tach isn't grounding out to itself.
4. My tach wire shows O.L. on the multimeter when connecting the multimeter to a ground proving that my tach wiring is not grounding out

Is it possible that some HEI distributors will not work with a reproduction of original equipment 1971 tachometer. The truck did not have a tach when I bought it and also I put in a new engine and distributor when I bought it so I've never seen a working setup in the truck .
