Hi All,

OK its good practice to remove the battery’s negative lead first, but all that happens if you short the power is the fuse pops. On the IE version you’d be resetting the ECU too, which may not be a bad thing

Also, the best option would be a direct feed from the battery if you have loud music on when lighting cigs and charging the phone. I’d guess the phone charger is plugged into the cig lighter, so won’t draw any where near as much current as the cig lighter, so you should be OK.

In short I’d say wire in a direct feed for the head unit if you find the fuse blowing too often, but don’t use a bigger fuse as the wire may burn through and set your car alight.

Regards,

OK so comparing to diagrams that's probably upside down, turning it over implies to me:

Red +12v ignition
Brown Earth
Blue auto aerial (hmm...)

Then various speaker cables but too hard to decipher for me but looks like blacks down one side? Not that it particularly matters and will be fairly obvious.

there are two blue wires.... and they definatly arnt areial... thats completely seperate

Nah I’d say brown is going to yellow.

Brown is the always live on all 4 Unos I’ve had – not the earth! and yellow has been live or switched live on all 5 head units I have hooked in (1 must stop loosing faces )

Paul means the blue wires are remotes for motorised aerials and power amps. The head unit puts 12V on them whenever it’s switched on to activate remote devices – normally blue for remote.

All I did was rotate it since I knew it was upside down, it's all from "cable side" as far as I can work out and if so, using the kenwood site, i've just compared, the second blue would therefore be illumination?

From the top of my head:
ISO CONNECTION COLOUR -- CAR WIRE COLOUR

Power end...
RED (Switched power) -- Car doesnt have one
YELLOW (Continous power) -- Brown (Continous 12v)
BLACK (Ground) -- Black (Ground)
BLUE (remote power arial) -- Car doesnt have one
ORANGE (Switched Illumination) -- Car doesnt have one

Speaker end...(negatives are striped of the same colour)
PURPLE - Rear Right
GREY - Front Right
WHITE - Front Left
GREEN - Rear Left

I cant tell you the speaker wire colours as mine were non standard and completely relaid all the speaker cables...

For the headunit to work in the uno, all you need it the ground and power wire (brown and black) connected up. Somewhere on the rear of the headunit to the ISO there should be a connector on the red and yellow wires. The red must connect to the yellow wire for it to work...

hey!
thanks for all the advice and info you guys are great! (and the welcomes)

so im almost there i think becuase of your help i have sussed it im just waiting for my bro to go out and buy me a fuse so i can test it

i found the thing what connects the yellow and red so i can connect both to the brown wire THANK YOU !!!!

as for the engine not starting i havent tried it today but..... apart from trying to fit the stereo theres only one thing i have changed/tried to fix on it

and i believe it the air filter well its the great big thing on the front of the engine with a big tube heading towards the rad
well that tube was split so my sis told me to tape it up with electrical tape till i buy a new one
and thinking about it i hadnt started car since then
did i make a boo-boo? lol

will let you know later how it went with the stereo once my bro gets fuse!

OK, there should be two tubes, one is a corregated aluminium foil type thing verticle up from the manifold into the bottom of the air filter (yes the big black thing), this is the hot air pipe and not strictly necessary, especially in the summer. There should be a second plastic cold air pipe from the radiator direction which clips onto the front.

Which do you mean? Either way, neither should prevent the car from starting, if there is a hole in the hot air tube (aluminium verticle one into the bottom of filter) this may lead to stalling in the cold, if the plastic one is like that the car should be ok, especially if it is taped up, the car may run better without a hole in it though, but probably not, this is where the engine gets its air to run.

A few questions, when you say it doesn't start, does it turn over or when you turn the key is there no noise etc. if no noise, that means battery could be dead to start off with. If it turns over but doesn't fire (i.e. burst into life) then, well, let us know which first

Obviously you haven't driven it much being a learner but have you noticed it stalling when it shouldn't at any point, i.e. sat at traffic lights and it just switches off? Maybe ask your sis.

Paul

p.s. i hope none of it sounds condesending, i haven't a clue if you know anything about cars,

hi paul!

non of that was condesending as i know absolutely nothing about cars i know most of what stuff is called and probaly about 20% of what most of it does!
but really am a newbie!!!

so anyway yes it turns over just wont quite fire
while i have it trying to turn over the oil and batt light come on
my sis says i have to use the choke to start it so obviously that light to
i did try with and without choke she still didnt fire up
im just about to go try now and ill take a pic of the tube i mean
sis did say something about its hard to start in winter and you have to leave the choke on for longer to keep her going but in the summer its fine

also there is a real strong smell of petrol after starting it tho isnt that kind of normal cos ive been in a few old cars that smell like that a bit?

anyway back in a min

ok she wont start

i took some pics and upped them here

https://www.fiatforum.com/gallery/showgallery.php?cat=500&ppuser=10674

there is alot of oil or grease or something on one side of the engine

but it used to start first time everytime before i taped that thing up and tried to fit the stereo???
wish i had left it alone now!!!!

battery and oil light should come on as far as i remember with first stage of ignition then go out when the car is running.

Forgot to ask whether it had a choke or not, since it does it's a carb model and not injection (I had injection), they have auto chokes. Your sister is right, you want the choke on a bit in the winter but need to remember to take it off a little later (it richens the mixture so you have more petrol as a ratio of air). If you have tried it both on and off and somewhat in between it's a bit odd. I learnt off road in a G reg uno with a choke and as I remember, aslong as choke was on, it would start whatever the conditions.

At least we have probably ruled out battery, I will have to let the others take over now since I am not sure what else to offer. Although, if you have only had problems when it is damp it could be damp that is causing it, i.e. water on HT (spark plug) leads.

I wouldn't really be worried about the smell of petrol, since it's running rich with the choke you're bound to get that, sometimes happens on my laguna too and there's nothing wrong with that. I suppose you could have flooded the engine with too much petrol, which I would prevent by turning over the engine a few times without any choke or throttle. Try not to leave the starter on for too long at a time, it could damage it and the battery.

Sorry I can't be of more help!

so i just leave it alone for a bit?

i just tried real quick when i tried it but i did have the choke on
but it turned over maybe 3 or 4 times i knew it wasnt going to start so just turned it off

im quite sad now!!!! had a week today and ive killed it already!!!!!!!!!

It's a she now is it?

Just seen the pictures, wouldn't worry at all about the tape, that's fine, there's no pressure etc. to worry about.

You're missing the corregated aluminium foil type pipe up from the manifold (picture_0244) the thing that looks brown with a hole at the top, there should be a tube that connects from that to the bottom of the air box where there's a little flap which opens and closes when hot air is needed/not needed. However, most people don't have it in my experience and is very unlikely to be the cause of your problem.

The oiled area isn't something to worry about too much, if you pull off the black cap where you put the oil in, (picture_0244 again it's the sort of cap/flap directly to the left of fiat badge on the airbox) is there any mayo type substance?

I doubt, unless you did something silly, could have affected anything by your stereo fitting, though, somebody can tell you this, can any of the fuses you may have inadvertently pulled out/knocked have an affect on the running of the car?

Paul

well she cant be a boy with a name like fifi!!!!

anyway the pipe you said was missing must have always been so i think thats ok?? do i need to get one?

and i only pulled out one fuse for the stereo to give to bro to make sure he comes back with right one!!

but.....
there was a orange fuse in the passenger door that i found when i had to take the panel off to fix the door opening and closing by the handle lol so i found a empty spot in the fuse box and put it in
maybe that was a boo-boo!!

Well apologies, I didn't realise it had a name

lol, what was the empty slot? It's possible it was just a slot for spare fuses.

You might want a tube there for the winter (it prevents carb icing and should help cold running, the pipe is a few pounds from Halfords I think)

For starting it, try this:

Choke completely in (don't use choke) - then as you turn the key to start, squeeze the throttle pedal, say about an inch maybe a bit more. What happens? If it starts running, then straight away pull the choke out.

I have to start it like this every morning. Having the choke out first, and then turning the key does nothing (the starter just sits there turning).

As for the pipes, don't worry too much about it for the moment. Aim to get it idling first.

All that oil is ok for now, but do keep an eye on the oil levels. It looks like a leak with the distributor/cam seal and/or rocker cover. Aim to change it later, especially if you plan on keeping your car for a while.

lol

ok fuses:

_ _ _ _
_ _ _ _
_ _ _ _
_ :this second one down is the empty slot
_

the fuse is orange with a 20 on it

but it wasnt in anyway so i must have taken it back out again!!!

nah still wont start!

my sister seems to think i flooded it shes just been here says it never did that before so i must have flooded it lol
i dunno i guess ill have to wait and see if it is flooded it will start after a couple of days right?

if it dont then i went thru the stereo saga for nothing lmao

After a day or two some of the fuel will have evaporated but I thought to get over flooding you just turn it over a fair bit with no choke or throttle. As a 6-7 year old playing "racing" in a car park whilst mum went to the bank I got a telling off for flooding our old car once

lol awwwww

im actually afraid to trouble the car now!!!! im not going anywhere for a few days in it anyway so think ill just leave it and hope for the best
and my sis did try for a bit to start it with no choke and just turning it over it nearly fired a coupled of times but then we thought we might kill the battery so just left it
