hi peeps,

any ideas why my s1 is not turning over, when i go to turn it the lights in dash just dims and u can hear the fuel pump prime and stress as i have the key turned over.This is what i've done so far :

with ignition off i've got 12.6 battery power at starter and with ignition on aswell.

checked the coil wires with tester and it reads 0.01 or 0.02 and then i kept the red positive tester on the + coil wire and put my tester earth, to earth on battery an it reads 12.6 again which would be going to my coil.

So from what i've gathered the coil with my ignition switched on to position 2, should have battery power 12.6 at my coil correct so its ready to fire up and spin starter motor?

or is there a different understaning to this which should be present when ready to fire the car?

cheeRS in advance

flat battery it sounds to me

rst in breaking

checked the switch wire on the starter? engine earthed?

Battery or starter is goosed

RScrew69

i've tried 3 batteries which all work as i tried on mates car then removed an mine does the same thing and doesn't turn over.

am i right in saying that when your ignition is on no2 ready to fire the coil wires should when u test them have full battery power at them? so in my case 12.6 volts?

cheers

RScrew69

what ones the switch wire?

i got the positive on starter that has leads from battery to starter.

then theres another little push on rubber plug like the coil wires have that goes on to another thread which i have seen on some rs's with a little 8-10mm nut on? is that the switch wire?


car was running perfect week ago, parked it up and now this out of the blue, so am well stumped to say the least

Will the engine turn over by hand at all

RScrew69

yep it turn over by hand no probs

Exactly what have you done first or was simply went to start and nothing then changed battery still nothing

I bet you have missed a wire on the battery or put 1 on wrong recheck them properly

RScrew69

nope flat battery swapped over 2 more and still nothing

the wires are 2 for negative and 2 for positive they are exactly the same as its been since i've had it.

if i run earth from battery to negative on coil the coil will have 12.6 power at coil ready to turn over with power is that not correct?

or does the coil only come live with the 12.6 when u actually have the key turned all the way over for it to spin the starter?

Barry R

iTrader: (3)

dont know about the coil tbh but there should be more than 2 wires on pos mate
my S1 had about 4 or 5 have a check make sure everythings is right
Is the starter clicking at all

RScrew69

starter does not click at all, someone has said trying to tow start it

Barry R

iTrader: (3)

Thats not the prob I am 100% sure its a wire off the batt mate 1 wire on neg thats it the big 1 go and check it

RScrew69

i will get a pic tomorrow mate

Barry R

iTrader: (3)

Please do
From what I remember I have done the same as you and put a live on the neg and it wouldnt turn over

RScrew69

on the negative i have the earth wire whcih is earthed on the inner wing, and i have a thin skinny brown wire on the earth aswell

the wires are definetely as they have always been, it deffos something else.

think i need to know the basics to actually spin the starter motor

sounds like your starters tired fella
check the voltage to the starter when ign off and when the trying to crank
also check that you are getting a live when trying to start on the solinoid (sp)
have you tried to bridge the starter at all
also check the connections from the ignition barrel to the main loom as these tend to corriode and have a bad connection
my old fiesta did this and it was the connections from the black box to the main loom

RScrew69

i done something in the haynes manual.
Said put headlights on and try and crank car over if lights dim the starter circuit has power.

i tried it and the lights do not dim at all when turning the key all the way over and holding it for a sec or 2.

how do u bridge the starter?

when the ignition is switched off where the 13mm nut go's and holds main positive cable for battery i checked that point to the both other points on the starter and it reads 12.6

i had a problem like this on my s1 turn the key and it just clicked tryed different batterys no joy tryed different starters no joy it had power to starter on ignition fuel pump works tryed earthing battery to engine liftting eye no joy then a mate said change the big red lead did this and it fired first turn of the key turn out the heat from the turbo damages the end where it bolts to the bell houseing

RScrew69

thing is when i try and turn key starter doesn't even click at all

moesin2005

just try it you never now if not what harm has it done

RScrew69

spoke to garage person he said to try it with red jump cable from battery to starter as a replacement wire and i should be fine

london_chris

have you tried to nbump start the car to see if the car runs?
sounds like ur starter is foobarr'd
there should be 2 wires on the starter, thick one, with battery voltage at it, and a skinny one which either clips on or is attached with a small nut,
the skinny one should see voltage when the key is in the crank position,
if it does and the starter doesnt spoin over the engine the starter has had it.
if it doesnt get the power feed with the key in the crank position then there is ur problem.
to test yr starter with the car in neutral, get a power feed from the battery/starter thick wire and bridge it to the little wire's attaching point on the starter solenoid,

push'd the car down the road me an my bro and it bump started in 2nd gear no probs and ran without any issues.

so would you all say its the starter to blame or something else?

it ran for 10mins no probs, parked it back up tried to start again and nothing at all, starter doesn't click or anything

cheers

london_chris

sounds like the starter,
but you need to test as above

Robs Frst

Deffo starter motor

RScrew69

right removed starter tested it and it clicks in and out perfect and spins up fine.

theres power to the starter aswell

the car starts perfect on a little push start

so i am thinking now it is either the ignition switch or my silver fuel relay which is bridged on constantly.

when i was bridging the starter motor with a screwdriver the silver fuel relay inside the car was clicking. so i am now thinking if it has direct link with starter maybe its burnt out properly now hence why it doesn't spin starter motor

sound about right?

Tondeur

sorry i have`nt reade every post but it sounds like the soliniod on the starter is knackered

very common problem on the turbo as the starter is the same on all cvh engine but the turbo exposes it to extremem heat which turn gunk to a paste then it just jams try

give the starter motor a good whack

bump toe start

all so jump it you may be reading 12 v which is nopt perfect but enough but you muight be low on amps which is the juice that kicks it over

oopssorry like i said never had time to read the whole thread

you say you got power to the starter im assuming you have no cranck live to the throw switch wire normaly little push on wire on the start soliniod?

if you have this then i would say it must be earth as this is all it need to turn over firing is a diffenet matter all together but if it bumps ect then it should be ok

test this and let us know

Tony
