Flamethrower/Ballast resistor Saga

[singapore stag]

Hi, I got in contact with carl Dudash of Retrorockets, here is the reply RE: flamethrower coils and ballast resistors,....

Sukhdev,

If you are running points you should keep the ballast resistor. If you are running an Ignitor you can bypass the ballast resistor when running a 1.5 ohm coil.

P.S from what is wriiten I deduce that since an ignitor is "electronic ignition" then the Luminition would not require a Ballast resistor either.

Just received the following RE: Luminition,...

Sukhdev,

The coil circuit resistance will be dictated by the Luminition system. I do not know what that system requires.

[align=left]I dont think you can assume the two different electronic ignition systems work the same. Lumenition has dwell control and automatic shut off of coil current. Ignitor is a simpler more basic system. Then there is Ignitor II which is more sophisticated than basic Ignitor. [/align]
[align=left]Lumenition website has some helpful info but I could not find much on the Aldon site.[/align]

Hi Sukh,

I have an Ignitor and a Flamethrower coil and I connected up as standard, ie using the in loom ballast resistor wire. I did this after some messing about with a new feed when I discovered that I had nearly 11 volts from the original wire. It works fine, but I'm not sure if it would work with lumenition.

I tried the flamethrower with and without the b/resistor today. I think the coil gotquite hot without the b/resistor. So I have taken the flamethrower off and literally threw it in the boot and put my old coil back on.

I will use the flamethrower when I can get aclear cut answer as to how to use it.:?:X

Doesn't this depend on what value the voltage of the coil is. If it's a 6 volt coil you need the ballast resistor or wire, if the coil is 12volt then you don't need the ballast resistor, the petronix is then connected straight across the coil. Terry

That's how I understand it Terry, and how I fitted mine recently - direct to my 12 volt coil, with no problems so far.

cheers,

Peter

.

My father has a flame thrower on his Daimler and it does seem to run very hot compared to a "normal" coil. If they are all the same (I do not know) then his is a 12volt with no ballast resistor.

Does this help?

Just foundthe Lumenitionsiteto answer my question,. RE: Luminition PMA 50 ignition and using internally resisted coils., in my case a 1.5 ohm flamethrower......


[align=left]IGNITION COILS [/align]
[align=left]There are three major types of ignition coil - Conventional un-ballasted, conventional ballasted and constant energy. Lumenition have ignition system compatible with all three coils types however the correct coil must be used on each system. Failure to select the correct coil may lead to poor performance or even premature failure of the power module.Lumenition technical bulletin No.3 describes in detail each type of coil but the following can be used as a general rule. [/align]
[align=left]Conventional un-ballasted coils.[/align]
[align=left]These are for use in ignition system that do not have a ballast resistor. The coils usually have a resistance in the range of 2.5 to 3 ohms. These coils are suitable for use with PMA 50, PMA 60 and PMAZ. [/align]
[align=left]Note: for these systems the coil MUST NOT have a resistance less than 2.5 ohms. Coils with lower resistance will induce premature failure of the Optronic power module[/align]
[align=left]Conventional ballasted coils[/align]
[align=left]These have a resistance in the range of 1.2 - 1.5 ohms and MUST be used with a 1.5 ohm ballast resistor. They are suitable for use with PMA 50 PMA 60 and PMAZ.[/align]
[align=left]Consent energy coils[/align]
[align=left]These are often referred to as ‘electronic’ coils i.e.a coil for use with an electronic ignition system.They have a resistance of about 0.7 ohms. The low resistance gives a very fast recharge time and is therefore excellent for performance and high speed running. These coils are compatible with Lumenition Performance Ignition system CEK 150, CEK160, CEA150 and CEA160 products.[/align]
[align=left]NOTE, Low resistance electronic coils are totally unsuitable for use with Lumenition PMA50, PMA 60 and PMAZ. Use of a low resistance coil on these systems will cause the power module or the coil to fail – or both![/align]

Good info here guys thanks. I've inherited a Luminition but did not know to check that I've got the appropriate coil!
