[Tigers] Tach

[Randall Antosiak]

 I have a stock tach with a Petronix 1, no additional electronics, and the tach works great.  There is one simple trick to get this combo to work: you take the loop out of that wire connected to the back of the tach.   That's it.  Hard to believe that it is so simple.  
If you try this and it doesn't work, what could go wrong:1) Tach needs rebuilding.  I had mine rebuilt at Palo Alto Speedo.  I think it was about $250.2) You are missing a part.  You need all the original parts, consisting of the plastic wire surround, metal frame, and thumb screw.3) You have the direction of the wire reversed.  This is easy to screw up.  The current flow direction has to be the same as the original.
