Hi jmac,thanks for the info,the n12 pulsars didnt have a ballast resistor,seen a few in the wrecking yards.i was heading towards the n12 coil,i have a aftermarket 5inch monster tacho.
thanks

any hei spec coil will do the job. you 'could' get one to suit a blue motor commodore (vh/vk and I think vc models, just not vb model which was still points) BUT the problem is the coil terminal on them is a male terminal, and the datto is a female terminal, so you'd need to replace a coil lead.

The only reason I mention the commodore one at all is because you'll often find that even though the coil spec itself is identical, the price for something that is a more frequent sale (i.e. blue motor commodore) can be cheaper!

SO the other option is to get a coil (any brand is typically ok, I've had no problems with bosch an echlin over the years, I can't speak for other brands out there) - anyhoo --ask for the coil to suit an XE/F ford with electronic ignition. They had basically the same hei ignition as the holdens of that era (both bosch if anyone cares). The 'workings' are the same, just the physical size/shape/package effectively changed (with respect to the distributor) so they would fit in the engine in question.

Also - you'll find on some aftermarket coils for the holden blue motor, they actually _are_ a female coil terminal, and they have an adapter plugged in on top to convert to a male coil fitting, to suit a female coil lead terminal. So you can buy the holden spec one, unplug that adapter, and you're ready to go.


I know a little bit about these coils because a popular swap on aussie vals is to use a hemi electronic ignition distributor (which was an early electronic setup that was electronically triggered but still used a points spec coil, and only had similar output to a very optimal points setup, except that it never wore out, so to speak)) - anyhoo that distributor could be teamed with a holden/ford bosch hei module (the signal from the hemi dizzy was, almost purely by chance, compatible with them) and a hei spec coil. And they work a treat.

No doubt you could also just simply buy a coil to suit an n12 pulsar. It seems fairly clear that the distributor from bprojects (or at least the advert I just dug up on ebay!) is based on that. I'd just suggest checking the price compared to the XE/F era ford hei one.

About the only other thing - these setups are typically designed to work with full battery voltage. Points setups have a ballast resistor (they bypass it during starting to give full ignition power temporarily) to reduce the voltage/current going through the coil and points, simply to help the points last longer, they'll overheat/weld pieces of one contact to the other and likewise and deteriorate a lot quicker with full voltage. The electronic setups don't have that to be worried about, and will in fact function below optimal unless they get the full voltage for which they are designed.

So unless the n12 pulsars ran a ballast resistor (and afaik they didn't) delete it from your setup. The easiesst way is simply get an dual male terminal, unplug each end of the ballast resistor then plug the wires together with the male to make plug and tape over them. That way you could always go back to a points dizzy if wanted or needed to. And be _well_ aware that the factory tacho won't work like that (or won't work for long) so you'd also ideally want to bypas that, or rewire it as has been discussed in another thread. IF your car has a factory tach, of course. If not, never mind this part!

Hi everyone,

i just purchased a complete electronic distributor from bprojects on ebay to suit A series,ive looked at the tech wiki on electronic coils which is best recommended.
Has any one used a nissan n12 electronic coil or others to suit this distributor?.

I was speaking to my auto electrcian saying if you use the wrong electronic coil could damage the electronic internals.
bprojects has a coil to suit but postage is a killer!

any help or information anyone?
cheers
