Hi members I have fitted a Electrex World Ignition to my D10 

It will not start it ? it runs OK on points but as soon as you change over to electronic it won't start/

The kit has been back to Electrex twice for testing and they had it for 5 weeks and said it was OK

I have just got it back and is just the same, I have had the engine running on points and fitted a spark plug in the electronic plug cap earthed it on the engine and is sparking ok.

I am at my wits end any suggestions,

I will let anybody try in a different D10.

Oh good, yet another post about Electrex world. Do you never look through the forum?

Hi Denboy.
              Does the Electrex CDI produce a spark? If it does then your problem is probably timing. You do need to check for a spark in subdued lighting conditions. If you look in previous posts, someone touches the HT lead to see if they get an electric shock. Not recommended for anyone with a heart condition or pacemaker. I don't like doing it 'cos I don't like pain but if you're healthy it won't kill you. Best to use one of those neon spark testers. I can tell you that they work with the Electrex CDI.
As Cocorico suggests have a look through the past forum posts on this subject.
A year or two ago I was asked to look into a problem with an Electrex CDI that did not produce a spark. The fault turned out to be that one of the wires in the 3 pin connector had not retained and had pushed back in the plug and was not making connection to it's mating pin in the socket. The member had returned this unit to Electrex and they had said,"no fault found".
I believe that this 3 pin connector was only used in the later versions of the D10-B175 CDI units from Electrex.
I think that you need to speak to someone at Electrex for help.
Good luck.
       Mike.

Send it back and stick with the original system which works? As they say, "If it ain't broke....."

As Cocoric says, there must be a million threads on this subject. Indeed another is running just now ** Please log in to view **

Hi

Not withstanding the build issues that are being reported with this particular make, I cant speak for electrex world but I have a Czech Power Dyno system on my D1, the critical part is the earth lead to the coil / ht mounting bracket, you can’t rely on the frame for the earthing

The ring tongue has to be directly on to the coil / bracket or it won’t work.

good luck

Thanks for your reply to my Eletrex ignition problem.

The suggestion that the wire to the CDI unit might be Wrong

Eletrex confirm Blue goes to White    White Goes to Blue.

Tried it on another Bantam still won't fire.

Have given up.

Have you looked in FAQs? For example ** Please log in to view **

If it runs fine on the points / coil system, why change? Did you read Sponge's latest posts?

Do you have a wiring diagram and know where these wires come from? Mike's diagram was pretty instructional and simple. And, as Cocorico mentioned, there have been dozens of posts outlining this process previously if you have a look through the forum, particularly in FAQ which is there specifically for repeated queries like this.

I have to say, if you can't work out how to connect it by referring to Mike's post, the existing wiring and using the internet, perhaps you shouldn't be trying to fix an important part of the electrical system. Please don't try anything similar on higher voltage.

Regards denboy  

White and Light Green go to the AC terminals on the solid-state bridge rectifier, either way round. Connect Brown to the -ve (negative) terminal of the rectifier and connect translucent (earth) to the +ve (positive) terminal.

This assumes you're sticking with +ve earth. If you plan to swap to -ve earth then things are more complicated.

Not like some other suggestions.

Sorry to upset you, but if you had made an introductory post giving us some idea of your skills (or the lack of them), plus followed the advice at the top of the forum about looking to see if your question had already been asked - which it had - then posted all your subsequent questions in the same topic rather than separate ones, you may have had more useful responses. I see you are approaching 80, but as I am in my 70s I don't see that as a factor.

I won't mention the topics that were already running on Electrex World and D10 ignition systems. Oops.
