Omega Electrical and Audio Help / Re: Another NCDC 2013 Satnav problem

« on: 25 November 2011, 20:29:00 »

Wooo-Hoooo. Fixed it. I managed to uncrimp the connector, clean up the cable ends and re-crimp. Plugged it all back in and after about 2 minutes, the debug display starts picking up statelites. Once it's locked onto (IIRC) 5, up chirps Nagging Nora demanding that "The destination is in the indicated direction".

So all I've got to do now is fix the bonnet release cable back. Oh - and finnd smoe nice kind soul wiyh a cheap CID for sale

Anyone know what the inline plugs are called in the sat-nav aerial wiring? They are smaller than F's, and larger than SMA's.

Tonight I wiggled and jiggled the connector in the kickpanel, but couldn't clear the short. So I bit the bullet, pulled off the OSR C pillar trim, and pulled the roof wiring out. Sure enough, wiggling and jiggling that connector cleared and made the short. I then pulled the connector off the end of the cable. And then the short was obvious. Whoever crimped this connector on wants a kicking.

I've searched high and low for the connector type, but can't find it. I thought about stripping out the telephone cabling and using that, but the telephon is female-female, whereas the sat-nav is male-male, so that won't work. I've cleaned the connector up best I can so I could possibly re-use it, but I really, REALLY don't like electrical bodges.

Any ideas?

Also - I noticed in one of the earlier photos..



See on the satnav cable - it says "Sample". Do they all say that, or were Opel being cheapscates and used engineering sample cable in my car. Gits.

I think the '12/00' indicates it can 'see' 12 satellites, but is using none of them - which, last time someone had that fault, was a problem with the navigation CD (i.e. the NCDC couldn't read it)..

Though that would seem to be contradicted by your resistance readings?

I don't think it can mean that, since the aeriel cable was disconnected in the footwell at the time. I suspect it means that it *thinks* it should be able to see 12 satellites (based on current time, date and last position) but it can only actually see 0 satellites. At least that's what I understood previous posts to mean.

Also the car is in a garage. Brick walls and asbestos roof, with a few high buildings nearby. So I'm not sure if it'll work there anyway. FM radiko receprion is OK though, so maybe,

also i dont think maplins do the actual car aerial , but they do an internal aerial dont know if they are any dood though 
http://www.maplin.co.uk/sat-nav-external-patch-antenna-48721

Bought one of these lunchtime. Unfortunatley - it's the wrong connector on the end of the wire, so you can't screw it into the Omeca loom. Shame - would be a goos cheap test and possible replacement for a FUBAR roof aerial unit.

Sounds like you know the fault is in the kick panel, where there is a connector for the satnav coax

Who knows? Kick the kick panel hard enough and some force will make it as far as the radio and/or roof aerial.

Anywho. Some progress tonight. Managed to get the sat-nav into Diagnostic mode. No camera, so pinching Aaron's idea, display shows...

12/00 HDP0.0 DG 13:06 A S0.0
N50:50:11. W02:38:35 H+0100 R0
N0- 0 N0- 0 N0- 0 N0- 0
N0- 0 N0- 0 N0- 0 N0- 0

Which is apparantly somewhere in Ludlow. So next step, lift the gearstick gaitor, defeat the parking lock, and start another attempt at extraction.

I modified my Halfords dual din extractors as shown in one of the other posts. after mich wiggling and jiggling it finally came out. Then the problem with the cheapo extractors was obvious.  They splay out too much, such that by the time they get far enough in to engage the clips, they actually miss. So note to anyone using these things - make sure you bend them so that the two arms are parallel when they go through the hole in the front panel.

Next step, peer into the back of the radio cage. It all looked pretty good to me - seen much worse on aircraft. So I decided to buzz check the wiring from the Din cage to the kick panel. Both inner and screen OK, and virtually infinate resistance between them.

Next up, something those in the know won't like - but i figured that if it's goosed already then to hell with it - i measured the input impedance of the satnav aerial terminal on the back of the radio - measured 10K ohms ish.

So I plugged the radio back in (partly to listen to the Simon Mayo Confession on Radio 2), and measured the impedance between the core and screen of the cable to the radio in the footwell. Measured minus 6K ohms ish. Funny measurement, but the radio was powered on, and as long as it isn't zero or infinate, then hey-ho.

So then measured the impedance of the cable from the footwell to the roof aerial. Ah-haa. Zero ohms - well 0.03 ohms once I'd changes scales on the DVM.

Next step - disconnect the roof aerial and repeat the test. Again still measured 0.03 ohms at the footwell. Aditionally, measured 0.01 ohms at the roof end.

So - It looks like I've got a short in the coax cable between the roof and the footwell - most likely at the roof end. Bugga.  I'll have a trawl through the RS and Farnell catalogues at work tomorrow, but these sorts of small RF connectors usually require expensive crimp tools to assemble which we won't have. Anyone ever replaced this cable?

The other trick I know about is to take a fully charged car battery, connect the negative to the screen and the positive to the core. Wherever the cable catches fire - that's where the short is  if you'r lucky, it'll clear the short. If you're unluck, your car burns to the ground

I'm at Bovington at the minute Malc, want me to pop up one night and give you a hand ?

Stu

TBH Stu, there's not a lot that can be done untill Vx cough up some parts. Might be tomorrow, or Thursday - I only get stuff ordered on a Stock Order, coz it's cheaper that way. I wasn't really planning to do much till the Weekend, but that wight get bu99ered up by the Brazilian GP - not sure what time the TV coverage is (all of it, not just the race).

However, if you're offering to come over and do an Autoectomy, or better still, give the car it's yearly wash and polish

Ok an update...

The Satnav worked for a few days, then became intermittent again. In the intermittent phase, it appeared for a while that if I kicked the kick panel I could get it to work for the rest of the journey. But on the next start, it wouldn't work. Eventually even kicking the kick panel wouldn't fix it, and it hasn't worked at all for over a year now. This throws suspicion on the kick panel connectors.

Anyhow, I've had multiple goes at getting the radio out to look at the rear connectors. Doesn't want to budge. Several people have also attempted removal at the ABS Bristol meeting using 'pro' extraction tools - Draper, Snap-Off etc. These have all also failed. The only suggestion was to leave the car unlocked in St Pauls for half an hour and let the local chavs get it out

Now the engine is in bits, and I'm waiting for parts from Vx, so I thought I'd have another go. Last night I removed the aerial unit, and checked the connectors again. I also removed the kick panel (breaking the bonnet release lever in the process!) and re-seated all the connections there. Still GPS got inverted. I've read the other threads about the diagnostic test screens, so I'll try that tonight. But, my question...

The car is an Auto. It's in Park. You can't move the gear selector without starting the engine. The engine is in bits. Is there a way to defeat the gear selector so i can get the radio out?

Also, anyone got a Maplins part number for the SAT-NAV aerial? We've got a Maplins here in Yeovil, so I could rule out the everything up to the kick panel. Is it A47FH ??

Cheers,
Malcolm

I'd just like to add that if excessive sealant was used on the cam covers, I would remove the sump and give the oil pick up a good clean out

Yes - This job started out 3 weeks ago as a "simple" service. However, I soon discovered "oil cooled" spark plugs. Since then every job on this car has been a nightmare - wishbones, ATF fluid & filter replace etc. Even the $^£% air filter box picked a fight with me - one of the screws is stripped and refused to budge and it took about 3 hours to replace the air filter. And I've still to jack up the rear and have a go at the fuel filter.

I'm also wondering wheter to replace the oil cooler whilst the engine is in bits. The header tank is clean, but the cooler looks original to me. The CTS sensor looks old too. But where do you stop? I expect it'll need a cam belt soon too. It's also got a noisey cannister purge pump and non functioning sat nav again. Still can't get the NCD2013 out, and needs two front tyres. Oh, and it needs a wash - but then those who know me will realise that's standard

Hmm, not as bad as I thought. I've been given the price of £90.26 per rocker cover by the local Vx dealer. AIUI, this includes the gaskets, so the "real" price is about £60 each. Second hand ones seem to be £25-35 each (eBay etc) Given the agrivation factor this job entails, I think I'm going to shell out what Vx want.

Cheers,

PS - I take it you don't want my Eutovision tips then. I think a certain RB is £300 notes up after the Lordi tip

« on: 20 November 2011, 22:36:37 »

I've read the stuff on here about removing the powersounder. I may do that, but I've a question. On the plastic radiator cover there's a pictogram which I take to mean don't disconnect the battery else the powersounder will go off. Fair enough. Then under this is another pictogram which I think means read the manual - then disconnect the battery - and then the powersounder won't go off.

So my question is - is the powersounder telepathetic, and it knows when you've read the manual Or alternatively, What does the manual tell you about removing the battery? I'm stuffed if I can find anything in my copy.

Cheers,
Malcolm

Crikey - that was a quick response. I suppose you all must have just finished watching X Factor and were just checking your emails before bedtime 

Anyhow, I'll pop into the Vx stealer on the way to work tomorrow and get a price just for a laugh. Then I'll deal with Robsey's PM and/or put a request in Test.

Cheers
Malcolm

Oops - Just read the PM's Its a 2001 Y reg 3.0 V6 Elite.

Omega General Help / Rocker Cover Help

« on: 20 November 2011, 20:55:32 »

Guys n Gals,

I attempted a rocker cover gasket change today, and failed. I'm beginning to think this car hates me. I managed to get all the gaskets locally (yes genuine Vx).After two hour of cursing I'd got both rocker covers off. Many thanks to all those who contributed to the OOF guides. However, I still haven't worked out how to get the trumpets out without using excessive force. They're out - but what a pfaff.

Then I started to clean up the rocker covers. At first I thought there weren't any gaskets at all, what with the amount of silicone sealant everywhere. Then I unearthed the groove the gasket sits in, and there it was - brittle as anything. I was starting to feel I'd found the problem. Pulled all the bits of gasket out and continued cleaning out the sealant. Then - bugger.

The grove the gasket sits in is cracked and split on both rocker covers. On the drivers side, the outer lip is completely missing for about 10cm. On the passenger side, it's the inner lip on one of the front corners. I'm reluctant to re-use either rocker cover, because I think the gasket will slip out of the grove in the affected places.

On the plus side, I cleaned up all the breathers. As far as I could tell they weren't blocked. Only a small amount of sludge in the big breather, and next to nothing in the plenium cover ducts.

I think I'm going to need a new pair of rocker covers. I don't have 250 posts on here, so can't put an ad in your parts wanted section. I realise I'm bending the rules, bit has anyone got a good pair of undamaged rocker covers just lying about anywhere? If I have to I'll go to Vauxhall, but I'm betting that I'll get raped. p/n are
