What's the consensus on "Lucas" coils bought new today ?. Are they as bad as a lot of the green box tat on sale today ?. If so, what are folk using in preference (other than old "proper Lucas") ?.

Anything in a green Lucas box is Chinese scrap, althogh it's the only option on most items now unless you come across old Lucas red box items.
Its pure luck with quality.

I use a Blue Bosch one on my 8 Port and it seems to work...

Otherwise i look to get used Lucas Coils. Most of them worked

Never really had a problem with old Lucas coils.

They may have had a reputation back in the day but they are far better than the absolute shite sold in green Lucas boxes !

Been using an Aldon one for maybe 15 years on the race car.

Thanks, I pretty much knew the current stuff wouldn't be worth touching. I had considered a Bosch Blue but even they seem to vary in quality and price. I see "correct" ones (whole coil is blue) in old style Bosch packaging for around £130 and "new" Bosch ones with just a blue label for about £35. Is it the same story with these new ones as with the Lucas ones ?.

I've got a couple of all blue Bosch coils Robin, unused but not boxed (came with all my Ford stuff).

Will check tomorrow to see if 12v.

'Distributor Doctor' who are usually good suppliers of Lucas Distributors, etc say their coils are:-

"Top quality 12 volt coil made by LUCAS in India with a screw in King Lead connection and 3 Ohms primary resistance. Proper shiny brown Bakelite tower, marked LUCAS & Positive & Negative symbols, with male threads , nuts & washers to accept either 2BA ring terminals or Lucas blades. It's a Sports coil equivalent to the old Lucas 45066 HA12, and 45058 SA12. Gold anodised finish, oil filled & complete with clamp as it's 55mm diameter, the same as the original Sports coils."

Cheers Andrew. Let me know the number stamped on the base so I can confirm it's what I'm after.

Thanks. I see "genuine" Lucas sports coils for £25 on Ebay, I wonder if these are the knock off ones.

I had a Lucas gold coil, the end exploded and all the oil came out.

Bosch blue on there now, but not been anywhere since to test it :lol:

Another option is this,

I’ve not had a problem with one of these yet, simple job to change the casing colour and add a period sticker to make it blend in

Modern Lucas coils are total shite.

I have had many fail on me with little of no use whatsoever. I do feel that the old ones were decent.

A good modern alternative that I have used on a few occasions now are the Remax coils available from Green Sparkplug amongst others.

I swapped to these a few years ago & have never had any issues, apart from when Adam drilled a hole through one :lol:

Cheers, another decent option by the look of it.
Is a coil likely to fail intermittently ?. The issue I have only appears after quite a few miles and never replicates sitting in the garage running at normal temperature. Last time I broke down I pulled the king lead off the coil, checked I had a spark, put it back on and it fired instantly. No corrosion on the king lead terminal, new leads I made myself, but the coil is of unknown origin as it came with the car. Would forcing the coil to produce sufficient output to jump the air gap "fix" it temporarily ?. Ofcourse I'm assuming it's the coil at fault only because it worked after pulling the lead, could be a red herring. Plus it has electronic ignition, Aldon Ignitor I think, again of unknown provenance, could be this that's failing intermittently.

Yes, the symptoms you describe are a fried coil. When the coil is cold it works OK, but as it heats up it becomes increasingly unreliable. Give it a rest and it will work OK for a while again.

What you describe is exactly what I would expect from a duff coil.

I'm a big believer in the Distributor Doctors products, including his India-made coils on the basis that he has a good reputation to uphold. I haven't needed a replacement for ages but when I do, I'll get one from him - with his reputation attached to it. An opinion based solely on my dealings with him and his stuff in the past

Anyone else feel the same

When it starts to fail, it seems to be more gradual than a complete failure. I originally thought it was fuel starvation as it just started with a drop in power that you can still catch and bring the revs back up by dipping the clutch, take up the drive for a short distance, starts to die again, then keep repeating until it eventually won't take any throttle at all under load. So it definitely gets worse to the point that it just wont start eventually. Is this what you would expect with the coil ?. I was convinced it was lack of fuel, until I verified that the supply was fine. I sat for a couple of hours last time and it just wouldn't start. I would have thought the coil would have been at ambient temperature by that time.

I went through the EXACT same scenario last weekend in my Lotus 7. Adam had left the ignition on all day & cooked the coil. I was going to swap it, but when I tried it, the car started OK so I left it. Next time out the car did EXACTLY what you describe. I changed the coil & it's prefect again now. Well, for the moment anyway :)

Perfect thanks Mark. "Lots Of Trouble" as they like to say :)
