electronic ignition

[ampwhu]

on my system i have the white lead connected to the coil as well or the car does not run

3 wires come from the loom. 1 goes to the plus on the coil, one goes to the minus on the coil. the 3rd goes to the dizzy. if you've connected the 3rd wire to the coil, where have you connected it? the plus or the minus?

[dalebrignall]

i think the white wire is the low tension lead its on the plus side of the coil it was fitted by a well known morris minor firm .

You need another wire connected to the coil. I've got 2 of these kits and have made the same mistake before. I'll try to remember to take a pic tomorrow, although it will be my youngest's birthday so am likely to forget...

that would be great

Hello Ampwhu,

from SimonBBC's website, connect the red to the coil +ve, the blue to the coil -ve, the coil should also have a white wire from the ignition switch to the coil +ve.

Check that you have 12v or so at the coil +ve, with the ignition on. Check the rotor is not touching the module or the gap is too big. If the module is OK then it should give a spark if the above conditions are met. If not the module could be U\S (you did say it was OK with points so the coil is working?)
These modules are sensitive to voltage spikes so can easily be destroyed.

I agree with Alec, you have to have a white wire from the loom with 12v on it when the ignition is on. This should be on the coil +ve. If you only connect the red and blue, then where is the 12v power coming from??
I think the other 2 white wires must have been fitted by a previous owner, going to a secret switch as a security measure to cut the ignition, because you would normally only have a 12v white from the loom to coil +ve and a white/black from the coil -ve to the dizzy.

Hi,

Here's the photo...[frame][/frame]

the loom is a new one, fitted by the previous owner. there are 3 white wires that come from the loom. 2 go to the coil, to the plus and minus and the 3rd goes to the plastic block on the side of the dizzy. when you fit the blue plug along with the module, there is nowhere for this 3rd wire to go. so the coil is getting power as it's connected to the loom! the 2 wires from the module go to the coil as well.

it's this 3rd white wire that has been made redundant thats causing me concern. i can't see where it connect's. it has to go somewhere. so does it go to the coil plus, coil minus or ????

Hello Ampwhu,

No it doesn't need to go anywhere. You didn't reply to an earlier question if those wires are just white or white with a tracer? Anyway that is academic. I would assume that only one of those is live when the ignition is on? That one goes to the coil +ve, the electronic ignition leads go to +ve (red wire) and -Ve, blue wire. That's it. Just tape up the extra wires. The photograph illustrates the connection as it should be.

Alec
P.S. I just had another look at the photograph and that answers your question. There are three white wire, except two are the same wire, with both ends exposed. Note the wire from the distributor which then connects to the blue wire, white with black tracer. Personally I wouldn't have another connection but take the blue directly to the coil and strip out the redundant wire.

Hi Ampwhu, can you answer these questions and we may be getting to the bottom of it.

yes, one of the wires has a thin black line. thats the one that goes to the plus on the coil. the complete white wire goes to the minus on the coil.

there is no problem with the wiring, coil, 12v supply or any of the wiring to them. as i said, i refitted the same dizzy with condenser and points and the car ran fine.

if this 3rd wire is not needed, then why was it used to start with? it obviously did a job previously.

[Alec]

Hello Awmphu,

there is no third wire. It is two ends of the same wire, one to the coil +ve and the other to the distributor. This is now being replaced by the blue wire which comes from the distributor and goes to the coil +ve. Just ignore the wire with the black stripe.
I don't know how I can make this any clearer?

i won't get to go to the lock up where the car is stored until the middle of the week. i'll take some photo's to try and show you what i mean.

[LordAnthony]

Hi,

Alec is right, the blue wire would go to the - terminal but it wouldn't reach so I extended it using the white wire with the black stripe which would otherwise be redundant.
The plain white wire carries 12v and is connected to the + terminal which also has the red wire connected to it.

[ampwhu]

i must point out that its an A30 i have and not a moggy. but they are the same in principal. there is definatly 3 wires.

[beero]

It doesn't matter that it is an A30, a midget, a mini or a Minor.
But from the photo it does look like Alex is right, there are only 2 white wires, although you have 3 spade terminals. One goes into the loom for about 3 inches and then comes back out. Just make sure the white with 12v goes to +ve with the red, and the blue goes to-ve and forget about the other white.

"if this 3rd wire is not needed, then why was it used to start with? it obviously did a job previously."
Yes it did do a job, it was connected to the points which you have removed.

[LordAnthony]

Yes - the white wire with the black stripe has 2 ends which could look like 2 different wires. If you want to be sure run a meter over both ends to confirm this on yours. I just used this wire to extend the blue wire to the coil. A bit messy I suppose but it did the job and at least there's no spare wires hanging around.

[ampwhu]

sometimes in life...... you sometimes doubt yourself and think, am i correct?

well today i popped up to the lock up where the car lives and had a quick look under the bonnet...... just to satisfy that i do indeed, know what i am talking about. i actually took a decent enough photo with my mobile phone, but until the wife comes home, i won't be able to put it up on here.

when i took the photo, it quite clearly shows 3 white wires coming from the loom. it also has 2 yellow wires.

yellow goes to the dynamo
2 white go to the coil and the 3rd white one goes to the dizzy. they are 3 seperate wires and are NOT connected in the loom, or anywhere else for that matter. this should be interesting.

the car still refuses to start.

[Alec]

Hello Ampwhu,

as far as I know the A35 follows conventional Lucas colour codes so there should not be a yellow wire to the dynamo, They should have brown as a main colour. Has this been rewired by someone?

However as I said several post ago, this is academic. Find which white wire is live when you switch the ignition on. Connect that to the +ve coil terminal and also connect the red wire to the same point. Connect the blue wire to the coil -ve terminal, tape up any loose wires and try a start.
You have the battery connections swapped to negative earth I take it?
