Spark plug cap.

Pulled this off yesterday. The brass screw in thing that goes in the cap stayed on top of the plug itself and a capacitor and spring fell out the cap, anyone know which way round they go back?

if it has fallen completly apart like that the only choice might be to replace it

[GazW]

The brass contact is threaded, it can be screwed back in.. Or is that irrelevant?

i would of thought the capacitor should of been contected to the plug cap in some way at both ends for it to work correctly

[GazW]

Its worked.. I've never seen anything like it before.. I took the other one apart and looked at the order. It screws into the ht lead, I imagine the screw turns into a plate inside the cap, then the charge must pass through the spring, into the capacitor which touches the brass, that touches the brass which obviously connects to the plug..

Forgive the horrific drawing, might be easier to see what I mean, the correct order is CBA

glad that one is all sorted well done
