Kz750G wiring nightmare!

So I picked up a kz750G 1980 model the other day. The guy I got it from had removed 99% of the wiring and it didn't run. What he left has no rhyme or reason to it. So getting the manual and checking the wiring diagrams there and here on the forum it seems there are 2 options.
1: Wire the points through an igniter to the coil. The diagram shows 2 leads coming from the points.
2: Wire a single lead from the points to the coil and the other side seems to provide power from the key switch.
After much trial and error I'm still not getting any spark from the plugs.
My points have a single lead which leads me to think the igniter isn't required.
Any help at all on this would be greatly appreciated!

Here are some pics of what I'm working with.

The ignition coil is supposed to have two wires connected to its primary terminals.

One of these two wires provides battery positive voltage to the coil's primary winding (presumably when the key ignition is switched "ON").

The other of these two wires provides a ground for the coil's primary winding through closed points.

Opening of the points is the event that causes the coil to "fire" throughout the "secondary loop" comprised of the coil's secondary winding, two spark plug wires, spark plugs, and the engine head.

An igniter is used with a stock electronic ignition without points.

An igniter is not used with points.

Good Fortune!

There might be a good wiring harness on eebbaayy.
You can use the electronic ignition from a KZ440 or 82-84 750-Twin. you'd need a 750-Twin timing advancer for elec ign.
note: the igniter in the pic might be from a 750-4.

edit: I would get rid of all of those mash crimps & lousy connections, then install open barrel terminals & connectors using a good open barrel crimper. the crimps are very strong, same as stock. ... cycleterminal.com

That's what I was thinking that I shouldn't need an igniter. When I wire the points to the coil and just a straight line from the battery to the coil I'm still not getting any spark. I have the plug pulled and grounded against the engine and nothing sparking across the gap when I crank it.

Weird looking coil. Is it an automobile coil ?
Not saying an automobile coil couldn't work but it might be worth while measuring primary and secondary coil resistance to see if
(a) continuity and (b) resistance values similar to those recommended in the manual.

It's the coil that came on it, but that's not to say it's the correct one....... Guess I'll break out the meter and check some things.

I think he's showing a closeup of the ignition switch (generic, aftermarket, car-type). I can't really see the coil too well mounted in the frame.

Be sure to have a complete path for the spark. That means both plug wires need a close connection to each other or the engine. If not you can damage the coil.

One primary wire should have 12v on it going into the coil. The other primary wire just goes to the points. You may have to take a really close look at the points area to make sure all of the insulator washers etc. are in the correct place. Make sure the engine is grounded to the battery (since that is what the points plate must connect to through the engine).

Yes, that igniter is for a 4 cylinder Kz, judging by the number of wires.

Presumably, the coil at hand is a dual output coil, meaning that it has two spark plug wires.

With the coil receiving battery voltage, and the spark plugs attached and laying grounded against the head, simply connecting and disconnecting the "grounding wire" should produce spark on the plugs.

Connecting and disconnecting the "grounding wire" replicates closing and opening of the points.

Good Fortune!

Ahhhh, yes. that never occurred to me.
I thought the pic was the 12 V end of an autmobile coil. Hope I hav'nt caused to much confusion

Seems like a mismatch of contact points twin and transistorised four ignition parts,

Ok so I got it running! Seems the coil was turned backwards.......weird I know.....I turned it around and the damned thing fired right up! Success!
Thanks to all for the input!
