I have gone back to stock.. bought a stock dizzy, coil, resistor and actually ended up with 2 sets of them!

I tried the bluebird dizzy with a brand new hec715 coil as i thought that would be the prob.. but no still sputtering just though a certain part of the range.. my next guess would be that the ignition module got fried by the killswitch.. funnily enough a brand new BIM024 module has arrived today!

so im thinking one of two things.. keep the stock setup and sell the bluebird setup complete with new module and brand new coil OR try fitting up the new module and un doing the wiring changes and changing the coil over then giving that a go again.. I found adjusting the rear adjuster screw made subtle but effective differences when troubleshooting..

not sure what to do really.. i have some friends who have points and have never had an issue with them and i have others who say the electronic dizzy changed their driving lives! so kinda caught in the middle of 2 camps! haha

Thomen, how did you go?

I should have read the start of the thread. I have the same bosch distributor with the same issues!

I am just trying a few basic things and I will get back to you.

I can't even get idle, very big backfires and weak spark on 3 cylinders.

unfamilia - yeah! it has been quite an epic adventure~! I've found someone on ebay selling gt40r coils with resistors but i dunno if that'd be the right resistor.. i guess it would but i don't like guessing!

clyons8 - some pics would be brilliant but I've decided to go back to the points system and once it's up and running ill sell my bluebird conversion complete with a brand new coil i bought today but for now it's a backup!

i really am beginning to think it's the module.. but i'd love to find someone who does dizzy repairs and just take the dizzy and coil to them and "say test and make it work" most auto elecs i've called want the whole car there but now i've removed the dizzy and coil to make way for the stock setup it's easier to just take the parts in!

for the stock wiring i only have 1 wire going to my coil + at present.. there's supposed to be 2 for the stock wiring i think but dunno how to track it down!

The cog that meshes into the cam shaft gear is located on the end of the distributor shaft with a roll pin. The roll pin is simply a piece of flat metal rolled over to make a shaft or sleeve, this sleeve (roll pin) locates and secures the distributor cog/drive, it's purpose serves as locating & securing pin. So at the top of the cog you will see a hole that travels right through the shaft out to the other side. And this roll pin is pressed or tapped into and through the hole to secure the gear.

The E15 dizzy almost identical to the A-series distributor [in it's lower half design] except that it has a different fitting at the end (not a spiral cog). The wiki article says to remove this and the A-series cog, from a A-series distributor will slide over the shaft except the shaft has no hole for you to put the roll pin through. So you need to drill the hole through the shaft so as you can then press or tap this rooll pin into and therefore secure the cog to the shaft of the distributor.

If you have a stock distributor at hand you will notice that when you pull on the cog there is a slight bit of movement, that gap is 'the clearance required' that you need to judge when drilling and installing the new cog gear.

I can upload some pics if you like??

i know how you feel tom, been chaisng around for wheel bearings for a 200b all day- tell them they are the same as stanza and get laughed at. most place need to order from the manufactuer... 3 week wait and $35 to $45 a side! debating if to try ebay.

i don't know if its a curve thing.. it really is some kind of electrical sputtering at a certain rev range.. most auto elecs i called really didn't offer much in the way of a can do yes i can look at it.. are there any good contacts for this kind of dizzy work?

either way.. i really really need a champion or echlin part number for a stock late model a12 ballast resistor.. repco, auto one etc aren't sure.. i went to see both today..

Cheers,
Tom

if it improved with the coil, could it be that it needs a regraph to match the motor? L20 and aseries have totally differnt requirements and curves.

I have had my spare elec dizzy regraphed and locked to suit my L16. was on another L16 but who knows what was done- it had a big cam of some sort(and thats sitting in my back yard to now that i think about it).


Havent installed yet but locked and regraphed im 99% confident mine will be a lot better too. I decided to lock it after it was regraphed as they couldnt get the right springs to limit the mechanical advance over christmas, so easier to lock it.

Hi John,
I just tried the dizzy with a bosch hec715 bluebird replacement coil.. the difference in the curve through the rev range was a beautiful thing.. alas it is still sputtering through certain rev ranges under load.. the only thing i could think of trying next would be replacing the module..
opened the casing and the wires to it all seem fine and newish!

seeing as ive had some amazing people help me out with parts and take time out to give wonderful advice I'll be going back to points and am happy to be doing so! but just thought i'd let you know i'd eliminated another factor and still no luck..

the prob is most certainly electrical.. wiring the ballast resistor will be interesting (thanks for the instructions) because i have a positive from the coil to the dizzy and negative from the coil to the dizzy and then a cream wire also connected to the positive which i can't trace back (it heads off into the loom but im assuming it's 12v+)

but as such! will have a brand new (used once around the block to test, bought this morning and have the reciept hec715 to sell very shortly either separately or with the dizzy!)

haha i think im a little crazy too.. I'd like to look at it and keep it but id like to have a points setup too as a spare..

I do wonder as alot of people have said the coil must be specific and mine most certainly isnt..

Cheers,
Tom

Hi John,
thank you for such an informative and complete post.. I will follow what you have said and try a combination of those out!
Regards,
Tom
