Any info on this ignition?

No one else has any info on these? Is it basically a Duraspark or similar?
 
It may be an optoelectronic unit. That'd be my guess.

For one of my Falcons I acquired a hacked-up front wiring harness. Its appeal lay in the period-correct aftermarket relay someone added for better headlights. Same situation as you're looking at - it's old, but if it works then there's cred in the sense of it being an "authentic" modification. Look how people charge for genuine old hi-po parts stickers!

Regards, Adam.

Meaning what? How does this differ from DS II or DUI? Not interested in authenticity really, just dependibility. Do you possibly forsee problems running something like this?
 
I have never heard of Wellstronic, but from looking at the picture it looks like a dual advance loadomatic (points) dizzy. I can only ASSume that it is an early WELLS brand electronic conversion much like the petronix and simalar systems. The body of the dizzy does not look like a DS and is for sure not a DUI. The DS modules usually had 2 cables coming out of them and one from the dizzy. Its hard to tell in that picture. Issues I have heard of on the conversions are that some of them use non standard rotors and the trigger mechanism may not be compatible with any other modules or control boxes other than the orignal so if it works and is in good shape and you can get the rotor you did alright. I payed $10 for a DS2 from a yard that had bad bearings but the core charge on the $50 rebuilt was $10. The yard one also had the cap adapter that saved me the $10 so I came out ahead not counting the gas and such. You still will want to upgrade your coil that is going to cost $30-50 new. Make sure your plugs and wires are in good shape and you will want to open up the gap on the plugs. A new module for the DS is $20-50 depending on the quality and type you get.

My guess is you are going to be better off down the road with the DS or DUI since all the normal wear parts are very easy to find from multiple sources. The DUI I assume has plenty of weight/spring combos and vac modulators available. The DS seems to have less but still can be done and is a little more work to access.

You will just have to post some pics when you get it and maybe someone can Id it for sure.
 
This looks very similar to a factory pre-DS1 electronic ignition I had in a 1974 Mercury Comet. It wasn't a load-a-matic, it just had both a vacuum advance (outer nipple) and vacuum retard (inner nipple) for emissions purposes. I can't remember if it had an optoelectric pickup or not, but I do remember what when the wiring in the pickup failed, Ford couldn't even get me a new one. They said it was a partial one year only ignition for late 73- early 74 and was superceded in mid-74 by the Duraspark I. I ended up changing the entire distributor and box out for a Duraspark to get the car running reliably again.

So I wouldn't like this unit for it's uniqueness and lack of parts availability. But since you did buy it, maybe you should run it and just try and accumulate some spare parts for yourself. IIRC I got rid of the distributor as a core trade-in, but I may still have that control box out in the shop if you are interested in a spare....
 
Anyone know if the DS1 used the same pick up method (and therefore module) as the DS2? Is the basic concept of how the advance weights work the same in all the ford dizzy's?

I wonder if the one Scott had is like the early mopar one that still basically used points to switch a transistor? I guess it made the points last longer but other than that there was no gain in performance.

From what I know of basic electronics technology of the time any kind of optical pickup would have been a big problem for that application. The dirt, vibration, and RF would have been a killer to say nuthin of the speed required. If it was optical I can see why the updated it after a 1/2 year. Something like a reed switch and a magnet would have seemed a more practical 'hi tech' system at the time but also not quite up to the task. Perhaps thats why the DS2 came out within a year and lasted till the 90's. Im not sure what Mopar did early on but the late 70's and early 80's seemed to have the magnetic pick up coil system like Ford & GM. The few imports I have seen apart had the same concept also.

Yea, sure, if you can dig it up.

Appears to be a standard points distributor with aftermarket internals. I would just put a Pertronix in it and call it a day.
 
Can you fit a Duraspark reluctor in there? It's apparently an inductive pickup like a DS unit.
