Has anyone on here tried the Jaycar electronic ignition kit with hall effect sensors?

Is it an alternative to megajolt?

There are two kits and the sensor to buy, total cost about $140 plus bits and bobs such as wiring.

Main Kit ($69.95) :

Ignition Coil Driver ($46.95) :

Alec I used to run the earlier version of both kits & I'm about to install them again on my latest project. I found them to be an improvement over the std dizzy points coil setup.
Biggest advantage, you don't have to regraph the dizzy, its just a matter of reprogramming for a new advance curve.
The earlier version allowed me to run two advance curves & was able to change to either while driving.
If you do decide to run the kits I have a few pointers you may need to know about.

I'd be keen on hearing any tips too, any interest in doing a 'how to'?

I built the kits 15 yrs ago, which was the easiest part of the project, building electronic kits is 2nd nature to me. I had a few teething issues with my install but knowing what I know now with my original versions the next install will be trouble free.
I need to view the how to build / installation articles that come with the kits, you can't get them online by themselves, to give you any decent pointers / advice, as mine were the original versions with a few after market mods & I don't know if they've incorporated these mods / circuitry with the new kits.

Patience will be your friend if you decide to go ahead with the project!
I'm not saying they're hard or complicated, just need to plan carefully!

Have you already purchased these kits or just looking at the moment?

Doing a "how to" would probably be more based around the actual install to the car not with the building of the kits!

I'm not planning one no. I have built plenty of Jaycar stuff before so I am aware of what they are like.

I see plenty of talk regarding megajolt and wondered if these were a valid alternative.

My car runs a SimonBBC electronic dizzy and I have no complaints as it was a direct swap over.

If I ever need to change it I'll probably look at something like this.

I have also run an earlier version and it was a big improvment over points. the two benefits where easy starting from cold and I could drop the idle down a couple of hundred RPM and it didn't stall and the over run went away

Once I have got it going again I will have another fiddle with the ignition system

How do you modify the dizzy to accept the sensor?

I robbed the hall sensor our of a lucas set up i had

points will work as there is no high current going thru them so they last the box of bits does the high load switching

Jaycar used to sell a small hall sensor

The points will ultimately be the weak point of the setup. It caused my car to be off the road for 6 mths troubleshooting! I believe a particular resistor in the high energy ignition I think needs to be smaller to allow more current through the points to keep them clean.

I would highly recommend getting one of the electronic points setups to replace the points. That's what I'm doing with the next install!

You will also find you have to extend the rotor button brass tip too!

Cheers Shane

points due get a hard time, they do what they do are suppose to do and are an expendable item

I do agree the hall effect etc is the way to go for sure

I have modified a MG metro Dizzy to fit my non Plus block and this works just as well.

Minis certainly like a strong ignition spark

I hadn't even considered using the dizzy to trigger, I just assumed a toothed wheel?

Slightly OT, but I know a lot of people use a 72-2 wheel inside the dissy to trigger a Megajolt, as per:

No offence, but putting a trigger wheel up there in the dizzy will give more spark scatter than having it on the crank.
You have slack in the chain, clearance in the skew gears, endfloat in the dizzy drive shaft, etc. And still a rotor, dizzy cap, moisture when it rains, etc.

I'd put it on the crank, go Megajolt and be done with it. Eh, Simon K...

yeah.... I looked at the jaycar kit (4 years ago now?), but it didn't seem nearly as straightforward as the MJ, and not as much backup from other people using them. The MJ support community is very active
