TVR S2 Ignition Coil
Discussion
Hello!
I have experienced several issues with my 1990 TVR S2 2.9 theese days: weird speedo, burned fuse... I think this is caused by my ignition coil. It is a completly blanck coil, so I don't know at all what it was.
I have changed it with one I had in my garage (stupid idea), a Bosh Blue coil, 12 Volts, reference 0 221 119 027. My speedo is now working fine, the car starts on key, but I have now some rattles when the car iddles. I think this coil isn't the right one.
I have ordered two new coils, thinking that one of then would fit, given for the Sierra 2.9:
- BERU ZS566, 12 volts
- BOSCH 0 221 122 450, the red coil, 14 volts...
The bosch is given as a substitute for the Motorcraft 102 72 83, but I wold like to be sure that it'll work... Any opinion about that?

Your Black coil is quite likely to be the original Motorcraft/Ford coil.
From the vehicle applications I can see for your Blue coil it does not appear to be suitable for an electronic ignition system?
I've found a supplier for the Beru but no details or application list?
The Bosch 0 221 122 450 should be okay I reckon?

I had to replace the coil on my S3 shortly after buying it because it was hesitant and misfired something terrible if it got too hot under the bonnet.
I bought one of these - looks a bit unconventional but does the job very well and never had a problem for the last 3 years - I was told that it is a direct replacement for the original wet coil Lucas DLB 125

In all of my 70-odd years, and many many cars owned or worked on, I have only ever once replaced a conventional oil-filled coil. And that was only through sheer desperation to try to eliminate the cause of an intermittant fault on a VW Polo. The coil was not the problem.*
So yes, they are unreliable.
* The problem was actually bits of sellotape in the fuel tank drifting around and clogging up the fuel strainer at the pump pick-up pipe whenever there was suction. It was invisible floating about in the fuel, and only came to light when I removed the the tank and emptied it into a container. For a while, that one had me going nuts!
The previous owner had part ex'd that Polo for a people carrier I was selling due to his expanding family.
I hope his mischievious kids didn't stuff bits of sellotape into that car's fuel filler!

Well.... I finaly went for a Bosh, made for transistorised ignitions, the engine runs better, but I still have misfires at low RPM...
MisterTee, could you give me the reference of your Lucas Coil? I'll try that one too. It both of them doesn't work, I'll know it's not that.
PS: Do you think that the Spark Plugs could be the cause?

No, I'd just keep trying every different make of coil you can find, you've got a few to go at yet Could be plugs, have you had a look at them?
Could be plug leads
could be distributor cap
could be rotor arm
could be ...............
Fair comment but how many coils are you going to try before considering you may have disturbed something (lot of wires and connectors in that area) while changing it?

Same symptoms with the Beru?- BERU ZS566, 12 volts
- BOSCH 0 221 122 450, the red coil, 14 volts...

The one you mentioned initially, the 0 221 122 450 ?there's no logical reason why that one shouldn't have worked perfectly Do you suspect you were sold a faulty one?
good news you're now sorted with your Long Life Lucas jobby
