Question Mallory Unilite distributer "module" question!

I've researched thru the "knowlege base" and elsewhere about this question, but can't find an answer yet.

How do you know when the "module" has gone bad in a Mallory Unilite distributer? By "module", I mean the photo optic thing that acts like points in an old style distributer.

I'm running a resistor as per Mallory's directions

But, I'm getting some funky things going on above 2,500 rpm's but idle and cruise is fine, just higher rpm's and heavy laods seem to cause a miss or backfire thru the intake, or something like that!

Anybody worked on these "Unilite's" before?

i`ve had a unilite in my coupe for over 5 years. when the module went bad,the car would not run.
keep an extra module with you at all times cause most parts houses do NOT keep it in stock.
hope this helps, good luck.

Usually when those modules fail the engine dies like fastford described. I would start looking elseware. You should also have an inline power filter as per Mallorys recomendation.

Thanks,
That's what I was thinking, so my problem lies elsewhere

I'll pick up an extra module someday ($100) but my local speed shop DOES stock them currently.

You can do an in car test to the modue to make sure it is working properly. Simply get a 12 volt reading off of the negative side of the coil with key in the on position. Then swipe a card thru the optics in the module. You should see a voltage drop to 3 volts or less. Then when you remove the card it should jump right back up to 12 volts. If it doesn't drop below 3 or less volts it is bad. Also if the voltage doesn't jump right back up to 12 volts when you remove the card the module is bad. 605 is the Mallory part number for a replacement Unilite, but you can also use Mallory E-Spark module number 6100M or ACCEL module number 2005.

Thanks for the reply.....boy, you went way back in time to find this post!!!

Good info on the part numbers, I still have the same car as in 2003. And, I now carry a spare new Mallory module with me.

The problem I described in the start of the post turned out to be a Badly worn camshaft lobe in my big-block Chevrolet motor. Distributor was fine, and I am still running the same distributor in the same motor, but with a new camshaft and related parts installed back in 2003

Being the new guy I was just checking out the website and I saw this post. I'm pretty good with the Mallory stuff so if you have any other future questions on it just ask.
