MG MGF Technical - Starter Motor problems

Ladies and gentlemen,

I have apparently got a dodgy starter motor in my 98 VVC. The wiring has been checked, and is seemingly alright, with suspicion lying now on worn brushes.

So, the questions...

1) Any wiring surprises that are worth checking? Could I have missed something?

2) Any suggestions to where I could source brushes etc for an F starter motor? Local auto electricians are reluctant to actually fix these things, or supply the parts.

3) If I were to try and source a new starter motor, what am I looking for? That is, is the thing used in any other vehicles? Can I grab one from another car?

Okay, that'll do for now. Hope you are all well and good.

David, who didn't get on the Highlander... *sigh*

David,

I see you went already deep into the subject :)
So the wiring of the starter motors outer connection seems fine. This almost makes troubles.

Another to check is the battery ground cable.

The MGF/TF had four changes at the starter motor over all the years.
Don't ask me about mechanical differences.
IMO they are all the same fixtures to the gearbox ??

I only have collected some data and cross reference P/N from bosch and other.

There are 1,1Kw to 1,4kw marked starter motors. Some have got options for spares and some haven't. Some should be for VVC engines, other for cars with aircon.
Anyway, IMO there is no clear line with it and I think it's impossible for workshops to take the risk and recommend starter spares.
The only do _plug and play_ and change to a new according to the car's VIN.

HTH and let us know what you can find out.

Thanks for the reply Dieter,

I will make sure that all electrics are checked. And if I end up taking the beast apart, I will let you have as much info as I can gleam. If any. :)

Well,

I have just spoken to my garage. After inspecting the 98 VVC unit, a 1.4kV model, and comparing to the only available alternative, a 1.1kV...

The 1.1 has been fitted. I will let you know if there are any problems.

Can't figure out why the VVC would need a higher rated starter, and it seems that the TF uses a 1.1kV starter anyway.

Thanks for your help Dieter, and your great web site (even though I struggle with Googlish sometimes :-)

The VVC engine has two cam belts and also the vvc function on the intake camshaft probably needs a little more cranking power to drive all those extra pieces.

So adding all that up is why it needs the higher rated starter.

Thanks Branko,

I will have to see how things work out. I will let folks know if there are any problems...

I thought that all models of the TF used a 1.1kV motor. Does this mean that MGR rationalised their power needs at startup, or did the F VVC not really need the 1.4kV version in the first place?

Or have I missed something?

All a big learning curve for me...

David,

What are the actuall symptons with this starter?

(I took mine out when I replaced my clutch and it looked to be a simple starter motor.)


Cheers,
Branko.

No life whatsoever from starter, as if no power was getting to it. Began as an intermittent fault a week ago, and quickly developed into not working at all.

First thing checked was the electrical connections, including ground wires, and what not (you can tell I understand what I am talking about, can't you :-).

I have been working today, so I have not looked at it since it was removed. Will know more in next day or so.

In the meantime, I have a 1.1kV starter working just fine, as a replacement for the 1.4 version. No apparent problems.

David,
that's what I thought
:o)
I daubt you ever will have any problems according to this different part.

May be it's the solenoid contact plate burnt ?
