thanks

tdc sensor

tdc sensor

it looks new though? anyway to test?

 

[coxxy]

not that i know of. are you sure it on the right way round

 

[stuart22]

i am thinking of the right thing the sensor going in the top of the fly wheel?

 

[coxxy]

my mate put his on the wrong way and it wouldnt start. i spun it round and it was away

 

[coxxy]

yep

 

[stuart22]

but i didnt remove that and it started before so why now? or does it just happen like a biatch of car

 

[stuart22]

any other ideas?

 

[coxxy]

have you connected all wiring??

 

[stuart22]

yea ive traced the whole loam i dont understand what way do the leads go on but surly if i put leads on wrong it would still spark but just at wrong time and there is no spark at all

 

[stuart22]

is there ignition timing to get right aswell? cos there is not dissy?

 

[coxxy]

how have you tested for spark?

 

[stuart22]

yea took plug out connected it to lead put against metal and turned over not a spark at all

 

[coxxy]

nah cant adjust the timing. need to figure out y u aint got noting coming from the ignition coil

 

[stuart22]

exactly what i thought can only be bad wiring immobiliser coil plugs or leads cant it?

 

[coxxy]

is the immobiliser turning off. wouldnt of thought it was coil or leads if it started before you done the gasket

 

[stuart22]

well i when i turn it over the red light goes off that means the immobliser is off? or not? it did start before i started

 

[sideways danny]

there's an earth to the back of the head at flywheel end, that i've missed before and it did this

 

[stuart22]

that is on two of them bolt in same hole checked that lol

 

[coxxy]

its gonna be something u forgot to reconnect

 

[coxxy]

have you got a ohm meter

 

[stuart22]

what one is hiding then cos i cant see any the onyl thing is there is 2 pipes coming off the rocker box one goes to the airbox and the other im assuming hangs as a breather cos there is no where to connect it to.

 

[stuart22]

can get one tomorrow

 

[coxxy]

test the coils
D7F Engine
Terminals 1 to 2 = 1.5 ohms
Terminals 1 to 3 = 1.0 ohms
Terminals 1 to 4 = 1.0 ohms
Terminals 2 to 3 = 1.0 ohms
Terminals 2 to 4 = 1.0 ohms
Terminals 3 to 4 = 0.6 ohms
HT Terminal to HT terminal 8.0 ohms

 

[stuart22]

sorry i am going to sound stupid now so i have two wires froma ohm meter when you say terminal you mean the connection t the top of the coil with four wires what terminal is one the left or right and what one is four and what is the ht terminal sorry for sound stupid

 

[coxxy]

the ht terminals are where the ht leads connect to the coil. not sure bout the pin number but if yo do the first 2 pins and they read 1.5 then they are pins 1 and 2. then the other 2 pins should read 0.6 being pins 3 and 4

right i got from work today a digital automotive analayser it has ohms on it but which ohm setting the loewest is 200 ohms and the highest is 2 million ohms i assume its 200 ohms but im not sure if it goes down low enough

any help appreciated

Stuart

You want the 200Ohm setting. Hold the lead tips together (fairly tightly) to see whether there is any resistance in the leads (usually is if they are fused). This can then be removed from the figure shown when testing.

 

[stuart22]

going outside now report back

 

[stuart22]

i couldnt get a reading? all i fouind out using the conntinutity was that the earth on the coil plug was would beep before the black piece it bolts down with but not after that seems strange to me?

 

[stuart22]

Do i need to turn it over to get a ohm reading? i got a flash a reading but then nothing. but also the black piece at the end of the coil earth a capacitor or something i think i get no continuity through it is that normal?

Any help is aprreicated

Thanks!!!

 

[stuart22]

changed the crank sensor today still nothing will change coil and leads tomorrow and keep updated
