no hot start...

[DavidL]

Suddenly running into this. If I try to restart the car whilst it's hot there is no response from the key just a click - solenoid?. Leave it to cool a while and it starts. I assume I need a new start motor? Hot windings, high resistance etc which settles as it cools. Anything else

As you say probably the starter motor, had this in mine a very long time ago and replacing the starter cured it. Martin over on the 968 and tipec groups might be able to offer a rebuild.

Yes I agree, starter faulty. Worth getting a 1.7kw unit if you get a new/re-conditioned one. Will crank over quicker.

I got one on eBay from a German supplier for £113 plus a tenner delivery 3 years ago. You do need to send him your old one. £137 now I see:

Thanks for the link. I'd spotted this 1.7kw on autodoc but no idea if Ridex parts are any good?

Got to be worth a go at £90 with a warranty. Looks to be new and no need to send your old unit. I have no idea about Ridex either, sounds like some sort of adult activity lubricant , but it wouldn't stop me buying one and see how it goes.

Ridex is Autodoc's own brand.

Spent the day replacing the starter, well nearly. The 19mm nuts holding it in place did not want to come off. Much hammering on my poor ratchet but eventually they did. I've done the daft thing and not photographed the wiring. I have 4 wires , 2 large black with copper terminals, positive I assume, one large red and black, this is the one that is missing in all the online vids, I presume this goes with the other 2 large wires? and the smaller 8mm wire. There's a thread from Blade in 2020 but clearly some of the replies have been deleted.
I've bought the ridex starter above but I'm not sure it is correct. Nearly but maybe not quite. The body is longer than the old bosch one so the heat shield doesn't fit so well, I can't bolt it into the main fixing bolt just the 2 on the solenoid and the wires are struggling to reach the terminals. I'll have another go later but I'm not entirely convinced.
One thing I do know is I'm too old to be crawling under it so next buy will be a scissor lift!

 

[DavidL]

So yes there's a problem. The solenoid connections are rotated. The solenoid to starter connection is at the top not the bottom so the positive wires don;t reach. The switch terminal is more or less in the right place, a bit low, (it's hidden on the old part but you can just see it) but anyway the terminal is larger so the connector won't fit. Yes I could change it but I'm not sure I fancy that with the level of skill I have ...

Hi David

I had exact same 2 issues with my 1.7kw starter. You can simply unbolt the solenoid and rotate it to the correct orientation. As far as the heat shield goes, unfortunately it is a bit short for the longer motor (and I didn't find a part number for a longer one, a job for David K perhaps!), however I bolted mine on to the places it still fitted to and have had no issues in 3 years.

Interesting as I thought my solenoid being round the wrong way was carelessness when it had been remanufactured. Quite possibly the S2 wiring is slightly different and the 1.7kw starter comes like that. But as I've said, it's a simple case of unbolting and moving the solenoid and Bob's your uncle!

Once it's fitted and working you'll be pleased with the extra oomph you get from it.

Edit to add: I seem to recall I had to change a ring terminal well as one was too small for the new starter. You may or may not need to do this depending on your new units terminals.

[DavidL]

which bit do you unbolt? There are 3 star fittings the other end of the solenoid. These?
Did your switch wire fit? Not sure quite what to do with that

 

[scam75]

The whole solenoid assembly needs unbolted and turned, so yes, if that's how its held on. I don't recall the fastener types.

All my wires fitted fine when the solenoid was turned round, just one of them needed a bigger ring terminal (and bolt to hold it on), so my switch wire must have fitted.

 

[DavidL]

ok thanks I'll give it a go. The wires will be long enough then. Yes it's the ring connector that is too small, or the terminal too big. Presumably you cut the old one off and replaced it?

 

[scam75]

Yes correct.

 

[DavidL]

Turned the solenoid, I only get 1 more option as the wire from solenoid to the starter is short so hopefully that will be adequate. Thanks for your help Stuart.

 

[DavidL]

ok so sadly this isn't going to fit. The terminal position on the solenoid is reversed to the original bosch part. There are 3 fitting screws in an equilateral triangle You can rotate the solenoid one third in one direction but that still doesn't allow the positive cables to reach. You can't turn it another third as the cable from solenoid to starter is too short for this. Almost but not quite. You might be able to catch a thread with the screw and tighten it but it would put the cable on a lot of strain. So back it goes and I'll start again looking at the terminal positions very carefully.

 

[scam75]

How annoying! I suppose you could have cut and spliced the solenoid to starter cable and extended it but not ideal. Mine is a remanufactured Bosch unit, maybe the body or set-up is different from what you've got. Must be very similar though as you were millimeters away from success.
