Re: Valeo clutch & Gearbox replacement

Hi folks
Got another prob with this motor. Altho she's not back on the ground yet, I've been starting her up and running the engine from time to time, but today she wouldn't start. The battery is ok, but the starter motor didn't even turn, not even a little bit. Only activity when I turn the key was what sounded kind of like the intermittent chirp of a grass cricket from what I think is the area of the battery/ fuse box area.
Any ideas,anyone?
Thanks in advance.
Cheers

Re: Valeo clutch & Gearbox replacement

When you pulled the starter motore out, to remove the bell-housing, did you loosen it and not tighten the electrical cables (particularly the earth)?

Or did you just unbolt it and not touch the electrics? It's worth a check that when you pulled the starter away from the housing that a cable didn't get bent, de-ranged or shorted out against the engine block (the latter would have blown a fuse though).

The starter is controlled by a relay.. so that may have decided to just pack up.. but that would be a bit coincidental.

Meanwhile, I looked up what the chirp of a "grass cricket" sounds like. I presume you mean a Roesel's bush cricket... rather than a Meadow Grasshopper, in which case that does point at the noise coming from a relay.

The relay itself could be knacked or it could just be not actuating well/fast enough because of a weak battery. I'd charge up the battery even if it's reporting 12.3V... it could have lost some cranking power, even if the volts are still holding up.

Re: Valeo clutch & Gearbox replacement

Thanks Ralph S.
I will check the electrical connections to the starter motor, altho I had dismissed this a bit because I hadn't disconnected the wiring from the motor when doing the gbox, just unbolted it and put it up out of the way, plus she's been firing up fine every time since the re-assemble.
I didn't actually test the battery as such, when I say that it is ok, that was from the point of view that all of the electrics seem to be working a they should - instrument panel showing fine and headlights nice and bright, and so on. Plus, initially I did think that there might possibly be an issue with this, so did the jump start thing, so should have been getting enough power?
From what you say might be the relay? Yes, it would be co-incidental, but its strange how often co-incidences do occur. Plus I've been severely rasselling about with the battery box, fuse tray and all of that recently, so don't know if that would have had some effect.
Cheers and thanks again.

Re: Valeo clutch & Gearbox replacement

Apart from the solenoid mounted on the starter motor, there are no relays in the starter circuit.

Check that the large black cable from the battery -ve terminal is clean and tight where it bolts to the top of the gearbox. If it's loose, it could produce an arcing sound from below the engine fuse box.

City boy.... so I've no idea what insect noise that would sound like.

How folks.
So the connections to the starter motor and the battery earth at the gbox all seem fine. Took the battery out and gave it a charge up, so the green light is showing on it, so that's ok. But things have gone from bad to worse - put the battery back in, still not starting but everything else as it should be. The buzz/ clicky noise was coming from the two relays (?) near the battery - the red and the black ones shown in the picture which correspond to T09 and T10 on the battery box lid and show a diagram which looks something like the engine management light on the dash. But now there seems to be some sort of almost total electrical failure - even when I open the door the courtesy lights don't come on and the dash doesn't come to life. The only sign of life at all is when I turn the key the airbag fault light comes on, nothing else happens at all, apart from that everything is totally dead.
Any ideas, anyone, at all?
Cheers.

Re: Valeo clutch & Gearbox replacement

Have you replaced the black master fuse board on top of the battery? According to the wiring diagram, there should be a red 125 Amp fuse next to the orange 150 Amp one. It looks as though there's never been one there in your picture.

The 125 Amp fuse supplies the ignition switch (H1) via the 20 Amp maxi fuse (F3, the large yellow one in the grey fuse box). If there's no power to the ignition switch, then the starter motor won't engage and turn.

Check that you have 12v both sides of fuse F3 with or without the ignition switched on. There are test points on top of the fuse, so you don't need to remove it to test for 12v.

Re: Valeo clutch & Gearbox replacement

Blimey! Where's all your wiring gone?

I seem to have a billion, if not thousands more wires in my battery box. They hardly fit.
Gerrard is an Active Air (which is ironic, since it's not "active" at all) JTD though...

Re: Valeo clutch & Gearbox replacement

Hi Davren

No, havent done anything with the black master fuse board at all (except rumble it about a bit, along with all the other gubbins in that area, when taking out/putting back before/after replacing the gbox). So, given that the car was running fine without the additional fuse to which you refer, before she was taken off the road and after re-assembly, I was surprised that this might be a thing, but I will certainly do the tests that you recommend. Ill also have a wee swatch at whats on the other Stilo, which might give me a clue as to what should be. TBH, anythings worth a try.

Im also going to try a different battery in it (Ive got a bigger, newish one in an old Volvo I have), to see if that will make any difference. The one that is in this Stilo is less than a year old and Im fairly confident that its well charged up since the green light is showing on it and when I had it on the mains charger after a few hours the charger showed negligible charging input. But, who knows, over the last few months there have been extended spells when the battery has not been in use, so you never know, and I am aware that strange things can happen with Stilo electrics when the power input is a bit not what it should be.

In relation to my previous post, do you think that the clicky/buzzy noise from the two relays (which has now stopped, along with everything else), has anything to do with things? And if so, I was thinking that I could maybe swap them over with what Im pretty sure are the same relays in other stations on the same board to see if that has any effect on the basis that the two that were making the noise are located in ports which are designated on the battery cover lid with an engine management type symbol are important to the core functioning of the engine/system (?), whilst others are for less vital operations (for the purpose of this exercise, at least), like fans. Does that sound like something I could try, do you think, or am I way off track and talking bo*****s (as usual)?

Cheers

Re: Valeo clutch & Gearbox replacement

It was the battery which was responsible for the "total electrical failure"- tried a bigger one from the old Volvo which I made sure was fully charged, and things have come back to life. I was duped into thinking that the old battery which was in the car was fine cos the green light was showing on it (and I had had it on the charger for a while). It was a cheapie off eBay, so lesson learnt. Unfortunately, while that in itself is very much a relief, the starter is still not turning, so back to the start (or not as the case may be!) on that side of things.......
Cheers
