the car lost power for a split second ,the instrument lights and gauges have packed up and the battery light is illuminated MID doesn't work
either .Any ideas folks
TIA Darren

Has the alternater given up and is only running on battery power???? :-/

This was my thoughts
Check to see if the battery is flat.
-
check the connections on your battery, something similar happened to me and it was cos i got a load of cak around the terminal connector when i reconnected the battery. cleaned it up and hey presto, works properly again! might be a similar problem?
-
the alternator was what i thought ,but why has the dash (lights gauges) stopped working .Its under warranty but i don't have much faith in the people who i bought the car off . Has any body have an idea the cost of an alternator for a 2.2 auto
-
The other possibility is that the fuse powering the instrument panel has failed.

i'll go and check them now :y :y

Same alternator as the 120amp ones on the older Omega v6??

No.
Check fuse F15......

No.

checked fuse 15 and it had blown, replaced it, 5mins later that had blown any ideas Mark
reversing light had blown if that has any bearing on anything

I'm sure I've had that fuse go, If i remember correctly it also feeds the relays for the A/C, self levelling suspension and other stuff, you'll need a wiring diagram to see what else it does, just start isolating the various circuits it feeds till it stops blowing fuses

Hi Zippo,
Try this link, it will show you what fuse 15 covers.

Did you get any luck?
hope you sort it soon :)

15-15A Reverse lamps, cigarette lighter, glove compartment lamp,automatic transmission, automatic level control system, cruise control, ventilation for rear door windows, position memory for seat and mirror adjustment
Ciggy light would be my first port of call. 5p's fit nicely! ;D ;D

I was thinking that too, they also have a tendancy to twist and short out... :o :o

the car has never had a cig lighter while Ive owned it , but i took it all out anyway and the fuse still blew. But everything the fuse is meant to protect still works apart from the instruments themselves i.e fuel /temp gauge .The only warning light i do have that works, is for the battery Ah well the joys of motoring :D

the wife has called in at a former dealers to see if they could shed any light on the problem ( iam house bound for a bit) .Mrs Zippo has just been charged £64.63 for tech 2 and been told the car needs a new battery and alternator , 10-15 minuets work £65 quid robbing git

Sounds dodgy to me. Neither battery nor alternator would cuase the symptims. They have seen the battery light and jumped to the first conclusion they could.
First job is to find the reason the fuse blows and fix that. I suspect there'sd nothing wrong with the battery and alternator. The battery light is on because its' supply fuse has blown!

would the tech 2 not pick up the blown fuse
-
would the tech 2 not pick up the blown fuse
No. I wouldn't say the Tech 2 would be as much use as a multimeter in this instance. If a fuse keeps blowing the reason needs to be identified first, and only once that's fixed should any further diagnosis be carried out, if necessary.
As I said, I believe the reason for the battery light on, is that the supply to the dash has failed, and this is confirmed by the fact that the fuse has blown.
The garage were wrong to charge you for a Tech 2 session, IMHO, because that was never going to help them find a short circuit.
Kevin

well that's an auto electrician baffled ,he's totally stumped as to what the problem is
I FEEL A NIGHTMARE COMEING ON
-
One step back to start with.
Has anything been disturbed, removed, installed recently?

the garage sort of admitted that they might not have investigated the problem properly and want to see the car again ,which they will if the sparky doesn't come back ::)
-
Well the next stage is to unplug the ancillaries one by one to narrow it down further inspecting the wiring around them as you go.

This fuse actulay powers:
15-20A Reverse lamps, glove compartment lamp, automatic level control system, cruise control, seat and mirror adjustment, radio, heated rear seats, sun roof, instrument illumination, window operation, cooling fan, headlamp range adjustment
So check the reverse light bulbs, glove box bulb etc as they are easy to do.

morning Mark ,even with the fuse blown the reversing lights glove box lights still work .The only symptoms are the battery light permanently on and no warning lights/rev counter fuel/temp gauge not working

What year and I will pull up the specific circuit diagram.

Is it DEFINATLEY F15 blowing becasue that powers loads of stuff....
Do the wipers operate (looks like it would only affect the rain sensors)
Does the backlight in the headlight switch operate?
Does the engine store/indicate a fault?
Rad fans operating?
Mid operational?
The favourite place to check would be in the engine bay around the ecu box
I guess yours is an auto and hence why the reverse lights are not affected.

when i check around the engine fuse box etc apart from blown fuses what else am i looking for

back in a mo just check
headlight back light u/s
wipers are ok
mid/engine management don't light up mid/ will light if i turn the side lights on
and its defo fuse 15

Ok, does the fuse blow with the climate off?
If it doesn't, try it set to eco....

go and try it now
it blows the fuse with the climate off or on ,what ive just noticed is that the fuse doesnt blow straight away it takes it a good 10 seconds to blow
-
ive just phoned the sparky to see if he is going to bother to get back in touch,To$$er said he couldn't get any info "how long did it take Mark to find the wiring diagram"

Can you remove K60 and K52 from the fuse box and re-try?

You could replace the fuse with a 12v bulb, if the bulb is on then you have a short somewhere (you already know this), this will save you replacing the fuse every time. When the lamp is off then the fault has been removed.

Ah yes, the old TV diagnosis trick
It would need to be a pretty high wattage one though as this fuse drives a few relays so we need some current getting into the circuit to diag...
-
Couple of headlamp bulbs in parallel or some 12v home halogen lights might do it. Work on one circuit at a time and try to keep everything else on that fuse turned off.

Pretty much impossible to keep things on it turned off as its basically the ignition on indication line so feeds lots of bits!

The other option is to fit the bulbs, turn on the ignition and work through the wiring diagram unplugging things until the bulbs go dim.
If you keep the major loads turned off I'd have thought most of the ignition feeds would just be driving relays.

i dont know what iam looking for Mark or where to look I know jack about car electrics
-
Sorry, my fault.
In the engine bay ECU box (triangular thing on the right of the engine bay).
Pull
Item 5 in the above diagram - K60 - Colour Green
Item 17 in the above diagram - K52 - Colour Brown

iam going to try it now Mark (i had to get some more fuses)
-
tried them both Mark the fuse still blows
-
i should have another sparky coming tomorrow , all things being equal and the wind blowing in the right direction

Thanks to all who offered advice and pointers.
In the end it was a short on the heated seat :y
Thanks again

would the tech 2 not pick up the blown fuse
No. I wouldn't say the Tech 2 would be as much use as a multimeter in this instance. If a fuse keeps blowing the reason needs to be identified first, and only once that's fixed should any further diagnosis be carried out, if necessary.
As I said, I believe the reason for the battery light on, is that the supply to the dash has failed, and this is confirmed by the fact that the fuse has blown.
The garage were wrong to charge you for a Tech 2 session, IMHO, because that was never going to help them find a short circuit.
Kevin
the wife mentioned your thoughts Kevin to the garage and they said its procedure to check for a short with tech 2 . The wife shouldn't have said anything really until i found out more about tech 2 and its uses , but that's blonde's for you :D :D :D

I'm not fully conversant with the Tech 2's capabilities. TheBoy / Mark'sDTM could shed more light, but I'd say a code reader would be about as much use as a choccy teapot for finding shorts. :-/
Well, glad it was sorted out in the end. :y

And you would be correct..........and TIS guides you through resistance and voltage measurements as a diag procedure for such things as well.
So they are a bunch of bloody muppets!
