I have a '72 240Z with a Crane XR3000 ignition system. Everything functions fine:classic:. I upgraded over the weekend with the addtion of a Crane HI-6TRC. Now the tach does not function:cry: . Does anyone out there have expereince with the 240Z type distributor and the Crane HI-6? the HI-6 does have a "tach output" but I do not believe this is what the 240Z tach requires. Any suggestions appreciated.

This is information posted off the emial list a few years ago. Hope it helps.

Hey Cary,

I suggest you install the 6000-8920 (not 6000-8910) with the second

wiring diagram http://64.90.9.168/cranecams/pdf/90008920.pdf . Use this

one

if you did converted the points to an eletronic system and want to keep the

early tach.

great! I new a "tach adapter" was necessary but not which one.

thanks
