    Latest coil recommendations?

    Bike started running on just 1 cylinder last week, so I did some trouble shooting and discovered that both front coils are dead. Likely scenario is that 1 was already dead or dying and it's taken the other one with it.
    I had no codes showing at all until they were both dead.

    I have swapped one of the rear ones into the front and the bike ran fine on both cylinders, albeit with just 1 coil running each.

    They look like the original sagem coils, so my question is, what is the latest recommendation for easy swap coils that I can pick up, which do not cost the earth?

    Are cbr 600 coils plug and play replacements? I'd rather not have to do a connector swap, as I suck at soldering. I've read about Renault coils too, but wasn't sure if those needed new connectors.

    I suppose I might as well get all 4.
    I've already got new leads from a fiat Brava fitted to the rear coils, as I had 1 loose spark clip. But it wasn't that. So ideally they would fit with those leads.

    Having looked about, I can see various car coils, some citroen/Renault etc which might be Valeo or other makes. Have the same connector, but have hard mounting sleeve which would need to be cut off.

    Has anyone had success with this, and fitting them back into the runner Sagem coil sleeve so they are easier to mount back to the Bike?

    So i ordered a set of 4 pencil coils from a Peugeot/Citroen v6.
    Same loom connectors, and they are Sagem ones.
    I just need to trim the hard plastic mount off and slip them into the rubber sleeve for mounting to the Fut.
    Hopefully then all will be well.

    Cost me the round total of £48 including postage.

    Unless you have different spark plug leads they are not compatible with the OEM leads without modification.

    I have a capo on the dyno strapped down right now that the ecu is not seeing coil failure but it most definitely has coil failure of at least one central coil. The ECU seems to detect this fault poorly.

    Hi deefred,

    I've got Fiat Brava 1.4 leads which i have successfully fitted to the original coils without issue, but I'm aware I may need to modify the bottom of the new coil to space out the connection correctly. I'm happy to do this though and will sort out that solution when they arrive and I can test fit. It looks like it's just a case of finding a suitable plastic spacer and affixing it to the end having removed the rubber covers.

    Yes, I had to manually test each one by running the bike on 1 cylinder at a time. Bike would start using just 1 coil on 1 cylinder and would run (roughly).

    If you loose a side spark plug it may or may not even be noticeable...if you lose a center coil/plug you will notice very quickly usually.

    I've been meaning to reply to this thread for a few days as I'm replacing coils and leads too.

    I initially got some used CBR coils then also picked up some Renault coils because they are new and no need to solder.
    I also got some fiat leads.

    I then found out the fiat leads don't connect positively to the Renault coils. The metal stud in the coil is slightly too small for the metal connector on the lead to click onto I think.

    I'm pretty sure I'm going to go with the CBR coils and M4 threaded rod to connect to the fiat leads. This method is well documented in the forum. I would have preferred to use the new coils but the coil-HT lead connection didn't feel great.

    Ditto as in trying to reply!!
    Apologies FuturaWales as I was going to offer help and then something comes up - as it does.
    If you had decided on going the CBRR route, I was going to offer to come down (nice rideout!) to help and solder the new loom into your existing one as I have just recently gone that route myself and found it much easier than I thought it would be and the result is just amazing!!
    Let us know how you get on and we can try to offer advice as & when

    Thanks guys! I appreciate the offer. I was in a bit of a rush to get something ordered because I didn't want to leave the bike sat for too long unused over winter. It's already been sat for a couple of weeks. So I did just go with what I saw as the simplest option, but that might not be the case.

    Not to worry though, if I do end up struggling with these coils, I can still go the CBR route and your assistance would be still highly appreciated!

    I'll let you know when they arrive and how I get on with them.

    Can you please try to measure the secondary circuit on the car coils. If it has the diod as the OEM coil, you should get mega ohm readings.

    Well this morning's testing proved as much as I expected. ECU on that ETV (same efi as RST) is not reporting coil failure, center front coil not firing at all under load and only marginally in free air gap. Needless to say swapping front leads from side to center was a revelation on the dyno, the graphs do not even look like they are from the same bike. Test rear cylinder first...no change to dyno output, swapped it back for fair test then swapped front cylinder, gained 15 ft/lbs of torque across the entire upper half of the rev range.
