Hi, as per the title. I believe this setup gets rid of the dist cap and rota. Less to wear etc. Anyone fitted it? Seen some of the site have it for sale but I've no idea what the wiring would be?

Hi Rob, the basic function of the ballast is to reduce to chances of Voltage and Current failure/overload in the ignition circuit, once the engine has started the corresponding voltage drop ceases and the ballast reduces the otherwise maximum supply through the ignition circuit. As far as I can determine as you have an electronic dizzy you don't need a ballast.

Hi Rob. I am trying to set up the same system as you using the wasted spark coil and an accuspark module. I don't seem to be able to get the wiring right - can you describe how yours is wired or maybe a diagram? Many thanks.Morning all, I am running a wasted spark set up also and from memory I’ve got an Accuspark system in the distributor. As life is a lesson I do not think there is a ballast resistor in there so that will have to be investigated and sourced if not, any info regarding this will be gratefully received.

Morning, I have a powerspark (same as Accuspark) but use a standard coil. I've not setup the wasted spark dual coil. I was investigating to see if worth it.Hi Rob.

Hi mate, I’ll take some pics and send you a description. Pm me your number so I can text/WhatsApp you as it’s easier for meHi Rob.

I have fitted a 'wasted spark' system onto my '695' replica using a Powespark ignition, a distributor cover from Ricambio and a Magneti Marelli coil p/no:--060717029012 (which costs about £10 exc carriage and VAT). If anybody wants some pictures of it, contact me [email protected]Hi mate, I’ll take some pics and send you a description. Pm me your number so I can text/WhatsApp you as it’s easier for me
I have used a standardI discussed this with a "long time" mechanic in Italy a few weeks ago. He wanted me to move over to the 126 wasted spark coil and he was adamant (despite my explaining about the resistance difference) that the ballast resistor was not needed!! I declined: of course, if the 126 coil is 1.5Ohm and there is no ballast resistor, it will burn out in due course unless a resistor is added.
I'm tempted nevertheless to make a proper job of it. However, surely if a 12v feed is taken from the starter motor solenoid (starter side) to the coil, the lever start will dispense with the need for a sprung type ignition/starter switch? ie pulling up the lever gives 12v to the coil for the short start up routing. When the starter lever is returned the 12v ceases and the 9v supply via the ballast resistor takes over to the wasted spark coil - or is this theory incorrect because there a point where the 12v and 9v are both being supplied to the coil (ie via the starter and via the ignition switch) and that's why you need a sprung type switch?
I cannot see this in practice because the battery is 12v not 24v!

As I mentioned previously, the Magneti Marelli coil that I have used (060717029012) seems to be a 3ohm coil. I have used it for quite a while now without any problem. It does NOT have a ballast resistor. Contact me direct if you want a picture of the installationI discussed this with a "long time" mechanic in Italy a few weeks ago.

thanks, the item i looked at was 1.5OhmI have used a standard
