Driving down the M27 the other day the engine suddenly cut out and the tachometer dropped immediately to zero. I coasted to a halt, waited a couple of minutes, restarted the engine and off I went. This was repeated five times on and off the motorway before it finally wouldn’t start at all and the car was recovered to home.

I’ve discovered a dodgy connector joining a single wire from the ignition switch to two other wires (a Lucas WT74 double bullet connector) which I’ve replaced and I’ve by-passed the isolator switch in the passenger footwell and now the engine starts.

My concern is that I’ve addressed a couple of possible causes but wonder whether there are others I should look at before going too far. The next big trip is to France and I’d really rather not have a known problem recur then.

Grateful for any ideas.

Mark
