rev counters will work on just about any spark ignition engine. The biggest issues are finding the coil wire and setting the rev counter to the correct number of cylinders which is the number the coil supplies not the total for the car. It is not very neat to take a signal from the coil. It is neater to take a signal from the ECU which uses the crankshaft sensor to know the revs. This is what fiat
Hi Malin I was told that the Sei does not have ignition coils like the cinq does hence this solution not working on the Sei. I have tried to do all the solutions on the FAQ but I cant seem to get any of them to relate to the Sei. I dont feel confident enough to start unplugging the ECU and start tampering with stuff there unless I know a cast iron solution that will actually work Is the crankshaft
Ok then my next question is where are the ignition coild located on my Sei or what should I be looking for Mikey543 I belive there was a ECU diagram on the FAQ for rev counters explaining what each pin is for if you havent already got it. Pin 23 is correct for attaching a rev counter to I have read that in someones fiat workshop manual that is where the signal. If you have identified it then it might
if theres a light on theres something wrong simple as. tbh you mechanic doesnt really sound like he knows what hes doin and if he does hes putting off workin on your car for some reason... httpshop.ebay.co.uk_fromR40&_t...All-Categories gives you an idea of how much it will cost try local motor factors (NOT HALFRAUDS) they may well be cheaper. easy unbolt rebolt job and a couple of electrical connectors.
Beware some mpi seicento has a common ECU fault. what year is your seicento could you post the number on the ecu Ming
Thanks for the replies.. The seicento is a 2001. So are these ignition coils easy to replace yourself Or does a garage have to do it Because everythings a little cramped in the bonnet of a seicento.
so easy even a girl could do it
it doesnt have an ignition coil in the traditonal sense. it has two coil packs that are triggered by the ECU . they are on the right hand side of the engine above the thermostat. they are the same coil packs as found on most of the fuel injected 8v fiat engines. clutch cables.. there is a design flaw with the clutch cable on the RHD cars. to go through that many cables though id say the clutch itself
Thanks very much for the info it was very helpful.. i assume that those coils are both the same & can be replaced individually i have bought a single one off ebay so hopefully i can just replace the faulty unit. I will check the clutch cable myself too to see if it has broken or simply become disengaged.. cheers for that. Oh and say hi to the rabbit pls.. its ears are mad nice one
Hi again i removed & tested the twin coil units (marked BAE 800) & one of them was open circuit on the secondary winding the other unit showed a resistance of 3.68M ohm.. now then the unit i got as a replacement is marked BAE 800B and has secondary resistance of only 7.23K ohm both have a primary value of 0.7ohm & are marked 12v.. Ive no idea what the correct values ought to be but considering the
The nominal value of the coils 20 degrees C is Primary 0.5 to 0.6 ohm secondary 6.6 to 8.1 K ohm IT has been known when they fail to fire HT back up the LT side and cook the ECU so always better to be safe than sorry
When i thought my ignition coils had gone my mechanic mate told me that usually once one coil has gone the second goes about a week later...something along them lines anyways. I thought you changed ignition coils in pairs Congrats on the ebay win.
Get yourself into a scrapyard take an allen key set and a 10mm socket with a ratchet find yourself a seicento (as these are the newest and most likeliest found i got mine off a 52 plate need them for my 16vt coupe) get them off put them in your pocket with your tools then get something small off the car like a blanking plate pay for that and walk out It works out much cheaper LMAO

I know and know of loads of people who take parts from scrapyards as you probably do to ive heard stories of sets of alloys turbo s and in some cases doors bootlids and bonnets going missing all of which cost hell of a lot more than 2 coils how the hell people take those i dont know So dont have a go at me
the coils on all the 8v fire engines from a seicentopunto will also fit just so you know. and the bracket it bolts too can be taken off and replaced with a scrap yard part (from a 16v. wouldnt cost you much. ALTHOUGH you will need instant gasket to put it back on and be careful not to break the metal gasket thats in there too -). but you would get to look at the gears that make the cams spin which is always nice P
could try other highstreet autoparts shops.. or a scrap yard
Can I suggest that you do a little diagnostic first. With the engine running and using something insulated remove and refit each plug lead in turn. Note which make no difference to the idling. Then swap the coils and repeat. Then you will know if its a coil problem or not. Cheers D
