Re-reading your first post (on this page at least) I see that you did say there was no change already. Saw it but missed the significance since for some reason I was thinking that he had seen a drop before.
You're right, it sounds fishy and the module is definitely not doing it's thing, as you say.
Gotta slow down and actually "read" what I'm reading.

Will do- buying it today. this could potentially be what was giving me problems ever since i bought this EB 9 weeks ago where it would just up and die randomly.

I really hope this fixes it! Thanks for all your help fellas, especially Wayne (68Ford) i definately needed another brain to look at this and his bronco is sick!

Pertronix makes a drop in replacment for the Unilite eyeball modules. I HAD a Unilite until it went bad (1 year?) and ditched it. The bulb thingy burned out. I would not recommend one to anyone.

Bosshoff, any idea where to find this?

I talked to Mallory rep, he said to buy the cheaper E-spark #6100M ($37)explaining that it was just as good as the more expensive #605 module ($89).

hope he is right, but he didn't even hesitate in his answer and when i said older unilite he knew the series and part number.

We'll see when it shows up from Summit... here's to hoping!

got the module installed today and she started right up. drove down pch for a few miles and then did some freeway driving home. she purred the whole way.

I hope this will solve the problem i had of the truck quitting randomly too... here's to hoping!

thanks again for all your help.

This could be my problem also. Right now I am trying to figure out if I have a bad coil or not Bronko69er is going to lend me one. If that is not it I think the module is the next choice. I have heard from several people that the modules on the Mallory's are POS, but I don't know from experence.

Good it's running

but be on the lookout for a new ignition system! Mallory is notorious for the dieing modules. This is why the Summit guy knew so much about your problem! I went through 2 modules (at about $65 apiece) over the course of three years before selling the Mallory Unilite to the next module buyer. I didn't want to buy ANOTHER module to carry as a spare part in the toolbox. Buy an Accel unit and have some confidence that the thing won't leave you stranded.

...or get a duraspark. If it does break you can pickup a cheap replacement part at nearly any parts store.

There's probably a really good reason that many of the high-end aftermarket magnetic trigger mechanisms from the big manufacturers look like a Ford Duraspark.

I've had more problems with the Pertronix Ignitors than with the Mallory Unilites. The older Unitlites were more sensitive to heat, dirt, oil and power spikes than most though. At least until Pertronix came along anyway.
And both of those companies have the same issue with their instructions. If you read it one way, you think you need to hook it up to power AFTER a resistor, to get lower voltage. Read another page or look at the diagram a different way, and you think you have to get power BEFORE the resistor, to run the full 12v to the units. Ugh.
And on Horsepower TV this weekend they installed an Ignitor and said to never run it to certain types of modern electronic ignition coils or you'll burn up the module for sure. Huh?

With either of those, just make sure you don't use the old "pull a plug wire and test for spark" method, too close to the distributor. It's fried more than it's share of modules.
So another vote for a Duraspark type setup.

Here's a new setup for the high on the cool-factor crowd.
Distributorless all in one compact package without a lot of wiring and controller box issues.

Of course, there's no guarantee that it's more reliable. But it's cool and spark output should be adequate. Wonder how it works with EFI setups?
