Are Duraspark Modules rebuildable?

Since around here, No one can test, or get new ones, are they rebuildable?
Is there a common component that pops?
Thanks

I thought they poured that resin all over the board. Unless you can get that off.

Yeah, the potting is going to be difficult to get off.
(not nearly as difficult as the Coltronics epoxy we used to bed boards in)

What usually goes is the transistors.
They live a hard life at 2-400x a second for years and years.

Even if the resin can be removed, where will the OP find parts to rebuild a DuraSpark module?

I know that Ford never sold the parts, so I doubt an auto parts store does.

In another thread, the OP said he bought two NOS D9VZ-12A199-A 'blue' modules...

There's no realistic way to rebuild one but switching transistors have come a long way since the '70's.

​​​​​​​Parts are cheap from Newark, Digit Key or Mouser.

Years ago I found a schematic(reverse engineered) of a DS2 modal. Windoze crashed on that computer and I lost that file.... never did find it and I have tried!

Next time in the JY if I find one that oozed out the sealant, I might grab it and reverse engineer it.....

I remember it was not a complicated circuit and used basic transistors,resistors and ect.

We do have a place in the Boston area, Needham, Ma it's an electronic "candy store" called U-doit Electronics, Individual electronic everything is there.
Wondering if rebuilding can be worth it.....

Hey Dave

We appear to have numerous "morons" here in the CT area when it comes to parts counter personnel, I was in Dallas last week and the Advance there had a module tester and checked out one I found in the Numerous (rare now in this area) junkyard.
It failed, new aftermarket are available.
Come back to CT and they either can't be bothered, or the Computer confuses them.
NAPA online shows the module and "Not Available" stated in the description.
I'm sure pressing the morons, I could get a generic module, but I'm looking fer NOS..

You know I did not look that close to the ones I found if they where in stock or not.


I saw your other post of getting 2 NOS units.
After what was said

I don't know if I would want to use 70's electronics as we know they fail.

If you want to give it a try, I found baking the module for an hour at around 350 will soften up that potting. Break up and pry out the goop carefully. Small flat screwdrivers and picks are your friend.

Oh yeah, cooking them will get the potting out.
Have you ever seen the pile of goo on the fender liner of a vehicle with an overheated module?

I've been thinking about reverse engineering these things for years. Will be very interested in seeing where this thread goes.

Like Eddie, I've seen a schematic of a DSII module before.
Maybe it would take a trip into the wayback machine to find it but I think if it existed on the web it didn't vanish completely.

Found these images. Now can anyone make heads or tails as to all the components?
