Hi Lapponia,
Yes you are right, sorry about that. The relay yoke/frame and armature/moving plate carrying the burnt contact are connected to 30, the fixed normally open / closed when relay energised (or when pushed by my pen!) counterpart contact (which is also slightly burnt but nothing like as badly as the contact on the armature) is connected to 87b. The fixed normally closed / open when relay energised contact is not connected to anything.
I only realised last night what you meant by "where to hide" the capacitor - I had forgotten how big the capacitor (or condenser as they were more usually called) across the points of an old style distributor was - item F in the picture below. Of course this wouldn't fit inside the housing of the DME relay. Do we really need a capacitor as large as this? And what about a zener diode, wouldn't that be smaller?
