Presumably this is because things like indicators/lights/windscreen wipers use
electricity (which is in short supply because of duff altenator) that is needed
by your injection/firing system.
You get similar symptoms when your fan belt is too loose (slipping) and the
altenator/dynamo is not charging.

1602.2 | Checked that...but... | KERNEL::BAYLISD | I know pigs exist, therefore... | Thu Nov 14 1991 11:13 | 15 |
| Hmmm....
The alternator has been replaced, (admittedly not with a bran new
one) but this made no difference. The regulator has been checked and we
were told it is okay.
The strange thing is that the battery warning light has ALWAYS
glowed dimly, I haven't been able to get rid of it. It has done this
from before this problem existed and yet has not glowed any brighter
since this problem existed. I thought this light was indicative of a
dodgy alternator/regulator but as the car has always started and run
perfectly beforehand, i've never worried about it.

1602.3 | Worth a try. | SUBURB::JASPERT | | Thu Nov 14 1991 19:57 | 10 |

I had an IDENTICAL problem on my injection Belmont.
Cured by Breakdown mechanic : Loose wire to spade connector on
alternator. No, I didnt believe it at first either, & I was very
sceptical about the fix. It never broke down again & the light never
glowed when the engine was hot.

1602.4 | But it's temperature related ! | KERNEL::BAYLISD | I know pigs exist, therefore... | Fri Nov 15 1991 18:24 | 8 |
| But my problem seems to be temperature related, and as the altenator
has been replaced once, any loose connections would have been found
and fixed.
Still baffled...

1602.5 | ? | NEWOA::SAXBY | Who left the O out of discount? | Fri Nov 15 1991 18:36 | 7 |

It couldn't be that you've got a chafed wire somewhere which parts as
the temperature increases could it?
Happened to me once, as the saying goes.

Regulators, once contaminated with oil, produce these symptoms. Work fine
when cold/warm duff when hot.
Regulators are pretty cheap to replace - compared with new batteries/
altenators/days worth of labour charges...

1602.8 | More possibilties | JUNO::JUPP | | Mon Nov 18 1991 13:58 | 27 |
1602.9 | | SUBURB::SCREENER | Robert Screene, UK Finance EUC | Tue Nov 19 1991 14:53 | 10 |
| I have a Golf with an identical fuel-injection system to your Mk1
Scirocco. If my alternator belt slips (such as after going over a lot
of the wet slippery stuff) I notice a momentary change of performance,
but as if the accelerator was let off half an inch.
Don't know exactly why this happens, as our fuel line is pressurised,
with a return line. If the fuel pump slows down it should take a few
seconds to affect the mixture. It's a possiblity though.

1602.10 | K jetronic frustration? | SHIPS::HALL_B | MPMs do it | Wed Nov 20 1991 15:05 | 20 |
| I presume that the injection system is a K jetronic. I would suggest
that you look at/have tested the fuel control/compensating pressure part
of the system. This is a rectangular block approx 3.5 x 2 x 2 inches
(aluminium) bolted to part of the engine so as to acquire the block
temperature (eventually). It has two fuel lines going to it, a vacuum
line and an electrical feed when the ignition is switched on. The
electrical feed is to an internal bimetal strip with a similar
characteristic to the cold start air bypass valve which also has a
bimetal electrically heated feature.
The purpose of the device is to provide a compensating fuel pressure in
opposition to the force from the air flow sensing plate. This is used
in a quite cunning way to provide acceleration enrichment and cold
start enrichment.
I would firstly check that this unit is seeing volts with the ignition
on and that the wiring to the bimetal heating provides continuity
inside the unit. Failure of the warm up part of this device would lead
to normal starting but overich fuel after warm up which seems to fit.

1602.12 | The problem, it gone !!!!! | KERNEL::BAYLISD | I know pigs exist, therefore... | Wed Nov 20 1991 20:39 | 15 |
| Thanks for the replies...
The problem seems to have gone away as quick as it came. There we
were standing in the cold around an open bonnet waiting for the car to
warm up so that we could have another play, and when it did, no
problem. The only thing we did was to check all the connecting blocks
on the back of the fuse box were tight.
So after, attempting to get the problem back, (by switching all the
electrics when the cooling fan was on) and failing we gave up. I'm not
confident that the problem has gone for good though, we'll just have to
wait and see.

1602.13 | Faulty fuse box | EVOAI1::MOULAERT | | Fri Nov 29 1991 20:31 | 7 |
| I had an '81 Golf GTI, and experienced the same symptom of dimly
glowing battery light. The problem has been solved by reseating the
cable (I think it was blue) coming from alternator on the back of
the fuse box. Later, the same happened, and I had to replace the fuse
box. I experienced 3 different problems on this car, all related to the
fuse box. I would suggest to wait, and if problem appears again, try to
replace fuse Box.
