Tach goes to terminal 1 on the coil. If you're running points this will also be the terminal the wire from the dist goes to.

I have an EI, my tach still connects to the switch side of the coil (- ?). But some of
these expensive units I believe need to be hooked up in a spicific way. Someone will be along shortley, why don't you have a seat. (IMG:style_emoticons/default/smile.gif) |

Tach goes to the (-) connection on the coil. I don't know what the Empi distributor has for connections; one will be power and one will be the output from the points (or whatever they have that replaces the points). The points signal goes to the (-) connection on the coil, just like the tach does.

Is it grounding out somewhere along that way?
A tach is pretty simple. As long as it is hooked up to the negative terminal on the coil, you should be functional. Zach |

do you own a dwell meter?
If so, hook it up as directed...see if the tach on the dwell meter works. If it does work, run a long jumper lead from the negative side of the coil to the tach and see if that works. If it does, you need to trace the stock wire for problems. If it doesnt, you need a new tach. Rich |
