Distributor pick up

[Shrinkdude]

I am trying to convert to a DS2 and running into some issues.
I don't think the magnetic pickup is triggering. I tried to ohm it with the orange and purple wires and I don't get continuity through it. I have tried to move the crank to the metal tab and tested with it in front of it and off of it. Is there a way to test it or is that it?

You should get a steady ohm reading (which I dont know) with the pickup coil all by itself. When the magnet is near or moving past the coil the ohm reading will be wacky because its acting like a generator and confusing the meter but at least you know that the coil is not open and the wires/connections are good (which are the most common problems).

What are you using for a module?

What is it doing or not doing?

Using a brand new one with the blue grommett. I thought it was the module I had in it, but it is doing the same thing. We are using a timing light to check for #1 firing and not getting anything (we have tried 3 different guns).
We have 12vdc on the red wire with the ignition switch turned on and the white wire going to "s". We pulled "i" off per the diagram off Mustangsteve's site. DS wiring
We are not getting the spark and thought maybe the signal from the pickup was bad. I'll ohm it out to see what it is, but I know there isn't low continuity.

.589k ohms either with or without the metal in front of it.

Seems like that should be in the ballpark for an ohm reading. I guess I should have said it would depend on the type of meter weather or not you get a change when you rotate the dizzy.

Do you have a Tach? Or tach function on your multimeter? If you do hook that up the normal way and see if you are getting a tach signal when you crank. If you get one your problem is the coil or something else in the secondary ignition system. If no tach signal then you are searching in the right area.

We found it!!!
We traced voltage to a bad connection and dirty terminals on the coil.
What a difference that DS2 made!!! I know everyone said it helped smooth it out, but wow! The difference in the way it runs is like night and day, so much better.

I wonder if it would have been as big a change in performance if you would have found the coil connection problem before the swap?

On mine there was not a big change. There are changes in performance and for sure lower maintainance and I still think it is a good swap to make but I wonder how many people have a problem with the orignal system when they make the change? A 'perfect' points system seems to work great on a 'perfect' tuned engine. The electronic systems seem to give us a little leeway to help out with other issues and it works or it dont compared to a points sysytem that can change over a short period of time and require tweaking.

I suppose I may be one of the few people that took out a good running points system, most people dont fix things that aint broke?

The connection problem was one I made during the swap. The wire pulled out from the connection but was still somewhat attached (visually).

Ahhh... been there done that.

My next project is EFI in my 73 cadillac and if that works same thing in the stang. Too bad there is not that many people that have done that because I bet I am going to have lots of dumb questions and wires that look ok. I have seen the efi section of this board but there is not as much activity there as in other areas, but even at that this is still one of the best sites on the net!
