Mallory Dist problems

[BOOT]

New as in NOS since Mallory is gone, clearly unused or ever installed and the place had more than one. All the research I did showed ford guys having issues, but all the gm ones I read they liked it and had no problems.

No springs or weights, programmable!

Alt test good.

[F-BIRD'88]

Processor in the distributor module is set up for wrong cylinder count. eg: 6 cyl vs 8 cyl. Plugin the lap top fire up the software and re set the
parameters.

cylinder count etc.. or reset default settings,disable internal rev limters, or launch, staging timing:rev limiter modifiers. and resave.

[BOOT]

I just reinstalled the alt and HEI, then tested at the dist 12ish idle and 14's with a lil rpm. Then I switch to 500 AC volts and got 40's at the dist, 30s at the alt but it idled down some.



F-bird It's and 8 plug cap so I don't think it has that option, well it has very limited options. Here are the tune options, it's very limited. This is not the tune I used just an example I made for a post awhile back, I used an even milder one for a safe 1st start up and planed to test later.

thats why i like dist testers and analog scopes.i know they are few and far between these days.but you can get huge amounts of data from them.no guessing.and you dont have to but a wrench to it.

and a vacuum gauge.

the principles of an ICE have not changed from day one.

We didn't fall for that .060 plug gap did we?

[BOOT]

This is an old thread about a probably defective dist that I checked everything I could on the car/set-up, gaps were never that big even tho it was a low 8ish comp engine and they were closed down from .040 to .030 w/o any effect. I plan to try it again with one of my upcoming projects, after it's tuned with a proven dist. Just to see if it's a possible wire routing issue in that car that won't be a quick fix. Then if not I may actually try and open up the dist and learn how to check them, if I feel like it since no1 seems to repair/test this model anymore.
