Replacement Lucas lrs109 starter motor for 1.6 MK5

[adamlab4 3]

Hi,

 

My 1982 Mk5 was starting fine , then suddenly just a CLICK from the starter solenoid I'm presuming. The battery was new a year ago and I have charged it over night (12.7v from it  prior to the over night charge) but still, the engine won't turnover, just a Click.

 

The starter looks like it's the original. I've taken it off and it's not jammed or seized. The engine can also be turned over with a spanner so not seized either.

 

The car has been used at least weekly and just had a big service and MOT pass a few months ago.

 

I'm guessing I need a new starter motor but can't find a replacement for a Lucas lrs109 anywhere. All those advertised as suitable on ebay turn out not to be when I send photos. I even got sent one guaranteed to be correct but it had two points of connection on the solenoid, rather than the 3 wires that connect to mine - main battery, ground and then another black and yellow wire which is bound together with the ground.

 

Any help would be much appreciated! 

 

Adam.

Most of the ones advertised have one small terminal  these are for ones with electronic ignition. Mk5 cortina (2.0 (82 only),Sierra, MK3  Granada, MK3 transit,etc all with factory electronic ignition 

You need one with two small terminals ( one spade, one bullet) for cortina 2.0 ohc( except 82 2.0) Mk5 1.6 ohc ( 80-82), all cortina P100,mk1-2 Granada ohc (-1982), Capri all ohc (-1982),MK2 transit ohc (-1982).

 

They earth through casing, 

Black/yellow is trigger,

Black is 12V non ballast to coil for starting,

Red main 12V power.

Hi,

 

As always - thanks for the swift reply!

Any idea where I can get the correct replacement?

A quick scout around on eBay produced zero new starters with the ballast connection.

It might be worth considering converting to electronic ignition, using a module in your existing distributor. You could then ignore the ballast wire.

You would need to fit a 12 volt coil.

Hi Tigdlo,

 

Thanks for the reply - I'm not a mechanic and don't have loads of experience so I hadn't realised this was the case. I have already fitted an Accuspark electronic ignition so am I right in presuming I only need to reconnect the battery and the ground? If this is the case, I have found a replacement for the Lucas lrs109 on ebay.:

A decent motor factors ,car spares ( rather than a Halfords chain store) should be able to get the right  one.

As unfortunately I only know places in Sheffield.

As you have found a replacement LRS109, just connect the wires as before.

Theoretically, as you have fitted an Accuspark unit, you should have removed the ballast resistor, and fitted a 12volt coil. However, assuming that the car has been starting, and running well, just leave it as is.

Hope that this helps!

Hi,

I believe the old one was 12v 0.8kW and the replacement one that I have found  listed as a replacement for the LRS109 is 12V 1.4 Kw High Torque - is it ok to use a higher torque version?

Thanks again for the help.

Yes should turn over faster.

Great - I'll give it a go and let you know what happens! have a good weekend!

Adam...try bench testing with jump leads with it off the car....I have Digbys in Heywood who refurbs starters

Hi, thanks for the reply!

I managed to find an exact replacement (uprated power) and fitted yesterday - back on the road!!! 

Heres the link if anyone else needs one - https://www.ebay.co.uk/itm/235080853909?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=2imszwitssk&sssrc=4429486&ssuid=RRdGTVtCR_G&var=&widget_ver=artemis&media=WHATS_APP

Does it have the terminal for the ballast wire?

[sheffieldcortinacentre 621]

Yes that's correct one for use with a points ignition.

[adamlab4 3]

Yes.
