Default Lucas RS1 Magneto help please

I have a Lister 26DH with what I believe is the RS1 magneto.

(nick named the hovis top???).

I have lost the spark.

Taking the mag top off to uncover the condenser I found the wire from the coil to the condenser barely attached.
#Ahh, that would be why I had a weak spark that is now no longer.... I thought.
That will need remaking/soldering.

So I undid the screw holding the condenser body to the mag body. This being the grounding tab for the condenser, with an intention of cleaning the connection to check for a good ground/earth.

The condenser fell to one side.
This I found odd as the 'live' end of the condenser was held by another bracket, by the same small nut that holds the wire from the coil.
The condenser body is insulated from this bracket by a sleeve.

It would appear that this 'live' bracket folds down inside the magneto body in down beside the magneto coil.

Only it is loose and unattached.

There is a 'tab' poking up from a nut down inside the mag body, that appears be bolted through to the points chamber.

Should this be attached where it looks to have broken off at this point?

Not having any experience with magneto's or even any stationary engine, I'm hoping someone can confirm that this bracket should be attached and not loose like the one I have is...

Thanks in advance for any information

short answer is yes. one end is bolted to the mag body the other end has a coil wire and the little bracket that goes through in the points chamber, if you want I can take some pictures of mine ( will be tomorrow )

Thanks Eddie.

It confirms my thoughts, so it looks like I will be carefully taking out the coil to get to that little nut down inside the body to rescue the broken bit of tab.
With a view to welding/brazing it back on to the bent bracket.

Do you know if there is anything to be aware of when removing the coil pack?

Then once back together, see if my condenser is still up to the job...

Thanks for the offer of the pictures, though probably no need unless you have them to hand.
