In Topic: Starter Grind

It was dead on the one occasion, (the following day, I changed the starter for a new one) I think that the lack of solenoid click was due to dirty contacts on the starter relay (mentioned above), there was pitting on the contacts, giving an ohmic reading, when removed from the fuse/relay housing and tested.

The only seemingly guaranteed method when it grinds repeatedly is to rock the car in gear a fraction, and that seems to allow it to catch.

 

I saw a youtube vid yesterday outline the issues of shimming the starter, so that the teeth do not mesh as completely as they might, were the starter to be bolted directly onto the engine.

 

Obviously, if the cogs withdraw from each other too much, then broken teeth can ensue, is anyone aware of a shimming practice related to Mondeo starters?

 

Thanks

Its not an electrical thing. It seems to be down to the starter cog / ring gear. After 2 grinds, it turned over after I rocked it in gear. Damned frustrating.

Yesterday I spoke to the mechanic who changed the clutch / flywheel (to a solid) 8kmiles ago, he said that there is a different number of teeth on the solid flywheel compared to a dual mass type. Hence a different starter cog. That's about the only thing that seems to make sense these days.

 

This suggestion was ridiculed by the starter motor supplier.

 

Can any one vouch for the number of teeth matching / varying between the solid / dual mass types?

 

Getting desperate now.

 

Thanks

Over the last week or so, the grind has continued. Hot or cold engine, standing overnight or stopped for 2-3 minutes. Totally random. I shorted out the link connector, so that contact resistance was eliminated. the first thing I heard when restarting - Grrriiiinnnd! so no luck there.

I located the starter relay  (K22) and opened that up, there was a little contact resistance, so it was cleaned and refitted.

 

Engine started nice, but then on restart - 'grind'. 1 out of every 5 turns was bad, which is an improvement. Next step is the battery. This one is the original 04 reg, and it drops to 11.7V just after the glow plugs have switched off. I'm hoping that its that.

 

I'm fearing the worst though, cos the only real solution is to rock the car in gear ever so slightly, to reposition the flywheel teeth.

Well, events continued last night, started the engine without incident at work and drove back, parked up, then later,  went out again, but on restarting for the return journy, key position 3 was met with nothing ,no solenoid click, grind or vroom. Stranded.

A call to the RAC brought a recovery wagon 90 mins later, where the chap took measurements and hit the starter with a steel bar. Hey presto it started, and I drove home to repark on 'bumpers hill'.

This morning I asked a local starter refurber for a price, bump started, went up and changed it for a new one. The old one had some filings and muck in it. 

On refitting and testing the new one, it did exactly the same as the other, final key position and no click, only red lights. Getting concerned here, I jiggled some wires, and it restarted, seems that the deadness was the sealed plug socket in line with the pos 3 / solenoid wire. So then I restarted it 10 times and there was no grind, whether instant start and waiting for plugs off light.

I therefore deduced that the grind was because of a duff starter, stated by the refurb specialist as a chinese type; 'they use cheap metal - ribbish' .

On paying, the telephone price suddenly had to have vat added, which if they'ed told me on the phone, would have been less of a sickener, anyway, it seems to be ok, onto the other faults now, on this supposedly perfect (according to the seller) car.

This is when the engine is hot. My vectra had lights that illuminated longer, the colder the engine was. (Perhaps there was a current sense cct on the glow plugs, so that if they are already hot, they dont have to heat up much more to reach 'pinch-off' resistance, whereas if they are cold, they have some way to go before the same high plug temp is reached).

Anyway, the plugs glowing for 4-5 seconds in a hot engine makes me concious of them burning out, which is why I tried starting prematurely.

I would have theorised that the current drawn through the plugs might be stopping the starters kick over, however , it has grinded (forgive that one) even after waiting 1 second after the plug lights had gone out. Once or twice.

It definitely likes you to wait until lights out before cranking.
