Fully charged battery. Tried a jumper from -ve battery to engine, still clicks, gave the motor a few whacks, still clicks. Is it donald :question
-
Sounds like it may be
-
Easy enough to do Paul?
-
Pass? ::) ::) Shouldn't think it's too bad :-/ :-/
They're normally pretty reliable though so I'd be thoroughly checking all the connections first ;) ;)
-
Bit fiddly as I recall...
-
Agreed. Check and check again all relevant wiring/connections. The starters dont often go wrong afaik.
If it needs changing the o/s engine mount needs to come off afaik, which I imagine means supporting engine from underneath until job is done. :y
Not that bad I suppose, and in your case, well worth the effort. ::) :-X :-X

Try applying 12v directly to the solenoid input before condemning the starter motor. It's not impossible that there's a bit of resistance in the gearbox starter inhibit switch or wiring that is preventing it from engaging fully. :y

Is that the heavy cable Kev :-/

Master once described the starter as bullet proof. He's not often wrong....

No, it's the thinner of the two, black and red.
Not sure what access to the starter is like, but if it's OK use a thickish bit of wire to connect it to battery positive making absolutely certain that the car is not in gear and that you don't short the cable to anywhere else and see if the engine turns over. (Alternatively, use a screwdriver to bridge the thick B+ terminal on the starter to the solenoid input.)
Additionally, you can put a multimeter on a Voltage range between this wire and the thick battery positive to the starter and see how much voltage drop you get when an assistant turns the key. Any more than a volt or two I would regard as suspicious.
If the black and red solenoid wire is the more positive of the two, this points to a problem in the thick B+ wire to the starter (it frequently becomes loose in the crimp at the positive battery terminal). If the black and red is negative with respect to the B+ wire, it points to a problem in the solenoid feed (high resistance in an interlock switch of the ignition switch perhaps?).

Thanks for the detailed info Kev, will give it a go :y

Starters hardly ever go wrong... I have changed only one (the other day)
Not a hard job but rather a fiddley pain in the arse job.
1. Undo the engine mount nuts, lift the to enable you to remove the Mount.
2. Remove engine mount bracket.
3. There are two Torx headed bolts E12 that hold the Starter to the block.
4. 13mm socket/spanner & 10mm socket/spanner to undo the two wires...

Another thing to try.. Turn the key and give the gear lever a waggle, and also try starting it in Neutral rather than Park. :y

It seems to me that the starter circuit is OK as the starter (presumably the solenoid) clicks when the key is turned. :y

There's clearly something there, but the solenoid needs lots of current to pull in fully, so if there's high resistance anywhere it can cause these symptoms.

Agreed. I'd be trying to short it out as you described to see if the starter starts the car.
And as you say, make sure the car is in Park or neutral as it's a pain in the bum trying to hold a car that's in Drive when you're stood in front of it!!! Been there ........ done that! ::) ::)

I`m trying to get bloody access to do that ;D ;D ;D

Never done it on the Omega, but as anyone who's had a 24v Senator/Carlton will tell you, the wiring to their starters was dubious to say the least, and I did it a few times on mine. :y

I shall persevere and if all else fails...............................there`s loads of bits to sell ;D

Right, put 12v direct to the starter solenoid, nothing. Tried again with key, not even a click :-/. Switched headlights and interior light on, tried again expecting the dash lights et al to dim slightly, nothing, all stayed the same luminance. Totally stumped now. Seriously contemplating sticking it in parts section

changing/servicing starter from under is a bit fiddly as I had the job done before.. but from oof I remember someone said its possible to take it out from up..
water tank and some other bits first.. :-/

Mine did, but no clicking, started as a Lazy Starter which I though was the battery, until a new battery nearly caused a melt down of the starter circuit............... ::) ::) ::)
