I figured I had fried my Mallory optical module with a battery charger, and so I just replaced it with brand new. Still no spark. With key on, I getting 12v at the neg side of the coil and on the primary. I had my fuel pump powered off the pos side of the coil, and was seeing a V drop down to just under 6 when that was on it. Moved the power source to the relay board. Now seeing 12v. Still no spark.

What the hell else should I check? Could I have fried the module on first power up? (IMG:style_emoticons/default/headbang.gif)

I started with a dual point because you can't buy a unilite unless you can find one used. Used VW single point and dual points are cheap and easy to find. I also went with the Mallory low empedence coil and found a curve kit with the gray springs. I definitely performs better that the Bosch distributor that it replaced. It starts easier when cold and hold an idle faster. It also seems to work better at high rpm.

I think you might have to buy a rotor for a regular distributor to make it work unless that hat piece on the unilite is removable.
