Howdy folks,

I bought a Jaycar high energy ignition kits to put into the datto a little while ago. I assembled it but have only just got around to mounting it today.

Has anyone had experience in the past with these? I only ask because mine isn't working at the moment.

There are 4 wires involved with the standard points installation (earth, +12v, - coil and 'from points') and I'm positive that I've just got them or even one of them going to the wrong thing.

I wired the earth (easy and it has been proven to work as I had something else working there before)
I had the 12v supply going to the +Coil (not sure that this was the best idea but i chose it because there was current going to it when I turned the key to 'on'.
One of the other wires I put to the -Coil (in the instructions this was pretty specific)

The part I don't understand is where the 'from points' wire is supposed to go.

Has anyone installed one of these and had it working? Where should I be putting the 'from points' wire and should I be taking any other wires out to put these in their place instead?

I hope that made sense, it's late. But thanks in advance guys.

I would have thought, to -ve coil, or to the box, to make it 'switch'...

hmm interesting...

so maybe have the 'from points' wire coming off the -coil and the -coil wire on the kit going to the wire on the back of the dizzy?

is that what you meant? I'm a bit reluctant to just give it a go, as I could easily fry the ignition kit with something around the wrong way... If I haven't already that is... haha

The way I would set this up is
+ve wire to the +ve terminal on the Coil
-ve wire to the negative of the coil
Wire from points. Would be the old -ve wire that went to the coil. Remember this box is now triggering your coil so you will have to remove the link in your old system otherwise the system just bypasses your new box and runs the standard system.

The trigger from the coil (the old negative wire) is now to goto the hi ignition box as it's now telling the box when to fire in which case it sends the signal down to the coil to fire.

I hope I have shed some light on this.

on a standard car, the points connect directly to the coil -ve.

With this kit the connection is broken.

There is a single wire which comes from the dizzy which connects directly to the points (pop your dizzy cap and have a look). This wire goes to the 'from points' on the HEI kit.

Then the HEI kit goes to the coil -ve.

The kit itself switches the coil now and the points are just a low(er) current 'switch' to trigger the HEI.



Remember to run a new wire to your coil negative instead of the old one so that the coil is no longer connected to the points.

EDIT - beat me to it

So this is what the diagram looks like...



and if I understand you correctly, this is what I should be doing, whilst taking off the old -coil wire going to the dizzy which was a white/black wire from what I can remember.

You got it

EDIT: The green wire is coil -ve - that's justa typo right?

If you connect that to coil +ve you'll blow the transistor!

cheers for that... I'll post results.

I think this is a job for tomorrow... thanks for you help.

bump for my edit above /\

haha, so it is... I really shouldn't have tried to get my point across using MS Paint at that sort of time.

but yes, you're right mate green goes to -ve coil.
