Problem was in another post with same title... 124 series 260e petrol 1991.
But to recap, drive through a puddle and engine either faultered or died.
Decided to give the engine a good squirt of water from a squeeezy bottle while it was running, all ok on plugs, leads ignition amp crankshaft pulley etc, but then when water hit the coil, sparks all over the place, and engine died. Closer inspection when it ran again, revealed a spark going from the centre part of the windings to the metal frame.
To cut the story short, changed the coil with one from a donor car, a Beru made one. Inspection of my original coil shows 4 cracks in the casing, and a tiny pin hole, which I assume was from where the sparking came from, photos attached.
Only put this on the site to assist if anyone else gets a similar problem

Yes near impossible to seal once a hole for the plastic will have turned to carbon, so pleased its running well now

Something like blue-tack might help in an emergency.

Nice to hear of some good hands on (or water on) diagnostics.

Nothing helps once leaking and holed, there are enough people who have tried fixing a leaking LOPT on TV sets, never found a thing that worked in my life.

One must also consider the implications of the output flashing to the primary circuits.
