I have scanned through the various Mallory threads but didn't find exactly what I was looking for so bear with me if I am covering old ground here.

I just purchased a Mallory distributor with a mechanical advance for my 1973 240 running triple Webers. I currently have a stock dizzy, stock coil, ballast resistor, etc.

Leading to the distributor, I have three wires - yellow going to the water temp sensor, a black wire and a green wire both attached to the dizzy. The green wire seems to just attach to the outside of the unit (ground?).

Can I just run the black and green wire into the new Mallory unit with no further changes (keep all the other components the same)?

I constantly hear about people who do and do not have tach problems - have we reached a consensus on whether this is a consistent problem? Is there a fix for it?

I haven't actually received the Mallory unit yet - can I expect decent instructions from them?

Thanks for any information you can provide.

(Note: Car is a 4-speed currently with a single-point distributor)

Mallory Distributor - or Mallory Unilite Distributor?

Carl B.

It is a Unilite.

DO NOT hook up the Unilte without reducing the voltage feed to it - you can burn it out.

This might help..

Mallory UniLite Hook Up<br> for 72 Datsun 240Z

the wiring there is for a 72 - and I can't remember if the 73 Tach is exactly the same or not.

FWIW,

I noticed you have a ProMaster Coil. I just have a stock unit. Do I have to go with a different coil too?

I don't believe you do… should be able to run with the stock coil..

Here's a little extra info, in addition to Carl Beck's. In case the unit doesn't come with its own or to plan ahead.
