Title: Stuck in Stokieland
Post by: Entwood on 24 May 2012, 14:13:33
Well, here I am, stuck in a layby awaiting Green Flag to take me home :) Alternate light started to flicker, came on steady, but would go out above 2000rpm, then needed 3000, then 4000,now on all the time. No multimeter with me but guessing alternator broke, hopefully just brushes.

Not very hospitable of Staffordshire IMHO.... :(

You got Daz's number?

He's away on a course.... :( Green Flag are on their way.

Regulator is the favourite, interestingly the 140A as fitted to the later cars is not quite as robust as the 120A on the earlier ones.

Seem to recall the reg pack being about 30-40 plus a tenner if doing the bearings at the same time

Now on my way to some place in Birmingham, they have sourced an alternator and are going to cover the labour cost...  I of course have to pay for the parts......but the job will be robbed....

Now if that Lovely Wife of yours had made the trip with you none of this would have happened  ;D

I personally would have been tempted to see if i could get home, even with the alternator not working.

Ive driven for over an hour, twice, in the Skudo with no alternator (last time was my visit to stoke two weeks ago when aux belt tensioner let go on the way back), everything turned off.....it made it both times and still had enough juice left in the battery to start it the following morning.  :y

Entwood isn't used to modern equipment... Only flying areoplanes  ;D

Hmm. Running loads on an Omega are quite high. Would have had to be a pretty fast dash home. ;)

Eventually back home ....

Reasons I didn't want to "risk" running off the battery

Electric fuel pump - I believe the Skudo is mechanical ??

2 X ECU's  .. petrol & gas

admittedly everything else could be turned off... would have been a tad hot ... !! but still not certain how long it would have lasted ...

My other worry ... as the thing was intermittent .. if there had been a sudden "return to function" for a few seconds .. then the alterrnator would be feeding a "flatter" battery than normal, with no back EMF ... this could (?) lead to a very high transient current or voltage surge which might not do all the other electronics a whole lot of good.... 

So options were fix or ferry home. I expected the latter, but when they sourced the replacement the rule book was half-mentioned .. then they offered to cover the labour costs .. essentially it was cheaper for them to do that than pay a driver to transport me to Bassett then drive back given the distance and the tacho rules ..

Given my committments for the next week or so, it was also easier for me to agree to that than to get home and start stripping the alternator out, then finding the bits to fix it etc etc.

:(

Diseasals don't require power to run :-\

Sadly us petrolmongers don't get that luxury :'(

Ummm.....what about their ecu/cam/crank sensor/injectors etc?? Also the fuel pump on later diesel scudo's is electric (its mounted in the fuel tank, so it doesnt require 'bleeding' if you run out of diesel)  ;)

True, but that's a much smaller draw than creating 6 sparks per revolution ;)

Not on a modern diesel there isnt.

Spark generation does not consume much juice and common rail injectors are pretty power hungry (consider they fire 8-15 times per cycle!  :o)

As for the surge Nigel, fear not, the alternators cant put out greater than the peek current and are protected against driving discharged loads. The potential voltage step would only be a few volts and the edge speed would not be overly great due to the current limit dropping the volts.

Simples!  ;D :y

Merci .. :)  Now if I had known that yesterday .......  :)

However, the job is done, Mr Mastercard is feeling fatter by a considerable amount :( but the car is driveable an I have no need to rush about like a wild thing trying to sort it before 1600 today ... when I leave for a weekend on the lash ... I have a large reunion to attend which will involve much drinking tonight, a formal dinner tomorrow, and probably require intravenous paracetamol on sunday !!! Work for 3 days then away in the tin tent over the bank holiday as I'm organising a function with over 40 vans attending, and numerous other activities including a garden party and a queen tribute band/dance !!

Just when was I gonna get the chance to fix the alternator !!!

:)
