hhmmnnn

bought a second hand newtronics optical ignition off ebay a few months ago.

red wire to optical switch in dizzy

then left with

yellow with spade terminal
white with spade terminal
blue with circular washer style terminal...

any ideas without blowing the thing to bits how i'd check what wires what?

have tried emailing newtronics but unsure if still in business (changed names etc)

any thoughts you guys?

I would have thought you would have a supply wire, ground wire, switch wire, and coil wire. I'd suggest the blue wire with the washer terminal is your ground. White supply and yellow coil?

According to this page, Newtronics have ceased to exist. They list the new email address as [email protected], they should be able to supply wiring instructions. I think a little experimentation wouldn't end in disaster, applying reverse polarity to a transistor system is not the end of the world, and biasing the gate direct with +12V just means it wouldn't work. I'd be tempted to wire the blue to ground, white to +12V and yellow to the -ve side of the coil. If that doesn't work swap white and yellow around. If that still doesn't work, step away from the car and await further instructions.

does away with the points - basically replaces with optical beam split with cut disk to get firing order distribution / timing right

ebay is a good source

The 1400/1600cc engines came with a electronic ignition system, I've never had to deal with contact points outside of lawnmower engines :)

There is a module, hall effect pickup & condensor in the dizzy, with two leads going to the coil. Power + to the coil and everything works.

Same module was used in a bunch-ton of GM stuff in the 70's and 80's.
