Electronic ignition part 3

I have now picked up the dizzy sensor, looks good at the moment i will wire it into the car once i have driven it a bit more.

One thing that will become an issue is the trigger magnets are moulded into the rotor arm. once this wears out i would have to buy another complete dizzy kit. However when this happens i will mod the rotor arm so that it locates on the cam in the dizzy and refit a standard rotor arm on top. Should work but I'll think about that when it needs doing.

I've done this due to the rotor leaving an additional 0.5mm gap from the rotor and the dizzy cap, it didn't work the sparks weaker. It did however let me get the phasing correct. It was about 6-10 degrees out from the standard setup.

As for the dizzy sensor the supplier warned me they have a lot of returns for dead units when people fit them to Quote kit cars. I think that probably means they get blown by the sort of wiring you find on many classics that overpower the coil on engine start. However more investigation seems to suggest that the unit should cope with the extra amperage of this type of wiring. Or at least the unit i have bought can. The unit has a transistor for the switching part which from the data sheet can stand 15 amps continuous load and 30 amps peak.

Anyway for my application it matters not as the electronic ignition unit stops high current going to the dizzy sensor.

I have now tried the electronic box and WOW what a difference the car need half the choke on startup and doesn't bog down like it used to. Best £13 I've spent on the car. It doesn't seem to increase power but refinement and throttle response are immeasurable better.

As above the phasings not that bad. So where do i go from here. Well the coil is now suspect so i will change that use the electronic box with a new set of points and leave it at that for now. I need to finish putting the interior in the car and play with the lamda sensor project.

This will then lead nicely into carb tuning and the dreaded MOT time - Joy. Electronic ignition will be looked at again when I'm not in the potential firing line of redundancy at work.
