Its the coil Roy

Post by billlobban »

I know we always say that 'its never the coil' well Matilda the Minor disgraced herself this afternoon in the middle of nowhere 60 miles from home up a single track road with no mobile signal - at least it wasnt raining :cry:
Short burst of misfiring then horrendous misfire got her about 100yds to a passing place.

I always take you lot's advice (well almost always) and I had an old coil in the back10 minutes later vroom vroom :)

But it proves the point its (almost) never the coil

Oh dear - even with cleaned up connections - it doesn't work if you refit it ? Although I say it is 'never' the coil - I do carry one with me at all times............... If the old one really doesn't work - throw it away to avoid future confusion - and get another spare to carry with you!

I've only ever had one coil fail in any of my cars - and that one actually gave notice by giving intermittant failures before finally giving up completely..... That was on a Ford by the way, not a Morris.... :-?

I had a run of bad luck with coils last year. The one that came with the car had riveted terminals and one of them came slightly loose on last year's MITHOS rally which led to intermittent misfiring but only under load at certain revs - that took a bit of time to diagnose. I replaced it with a 'new' Lucas one that had been in my spares box for over a year (so it was out of warranty). It lasted about a fortnight then failed completely on the motorway on the way to last year's National (a wire inside it fractured). She started misfiring badly shortly before the exit to a service station, spluttered and juddered up the exit road, and cut out completely at the entrance to the car park with just enough momentum left to coast into the first available parking space! I had another spare with me so I was quickly back on the road. No longer trusting the new ones, I bought a few used coils at the National. IIRC two of them turned out to be the wrong type on closer examination, one of them (a Lucas 'sports' coil) got me home but died a few days later, another ran for about a week then sprung an oil leak, and the final one is still working OK.

If it doesn't work, you're not hitting it with a big enough hammer.

Yes, I have had a couple of coils fail on me.

One was because, like Alex the rivetted connector broke loose. (is it possible to repair these with a new rivet??), another coil, the clamp worked loose and wore a dent/groove in the case, the coil failed and was too hot too touch.

I have seen another members car stop on a rally with coil failure- again a very hot coil.

So, although rare, they do fail on occasion.
Cheers John - all comments IMHO

Hi all, my dad had an A60 van years ago when he got it it had a very old coil fitted and he replaced it with a new lucas one, it lasted for around three weeks before it failed, when he looked to see why it had burst and was on fire on the engine, he put the old coil back on and it was still working ok when he scarped the van years later, just gos to show the old parts are better made than new patten ones, Mikey.
