Iwill try to take some pictures with the assembly process.
It is not different from before. The ground wire I solder it to the shroud to ensure good connection.
If the units are the potted ones from any of the ignitions manufacturer...the only option you have is to take off the existing cap and to save the "length" of the wire as much you can. Then solder the resistor, shrink tube-it, use electrical grade silicone, smear some over the wire...not much, insert the wire in to the silicone booth, make sure resistor lead is not too long and "poke" the booth on the other side and short it out.
get the ground braid over the S.S shroud, clean the shroud previously with some sand cloth, solder it. Pull the shrink tube over; heat it up and you good to go.
If the wire is bad, on the coil side, it can be repaired but it will take more time and effort to do it.
You will have to "destroy" the box and careful to detach the coil out and get a coil assembly I have. But after that you will have to be re creative with the box again ...use a large shrink tube to hold it together....
However, I do not think is worth it and cannot say that all this process will fix it if something else is wrong with the module inside.
