Did you buy one of the harnesses that I make? My eBay store is Enduro Doctor.
I send a diagram with my harness showing where every wire goes.

The ignition coil wire plugs into the main harness. The black wire it plugs into comes out of the harness at the same location as the black grounding ring terminal.

Welcome! from the UK.

Photos of mine attached.

Likely to be a single (albeit fed by 2 wires) female bullet connector exiting the main harness just in front of the part label - attach this to the male from the coil.

Do not, repeat, do not use the single black wire exiting the generator harness, roughly level with the carb - this is a points diagnostic wire and you won't get a spark if wired to earth.

The white wire from the generator is spare.

The coil plugs into a black wire that is electrically the same as the 2 black wires coming from the magneto.

I agree that you should not ground those wires... but I don't think that is what he is doing.

Battery should have a ring terminal that grounds to the frame.

That doesn't sound correct.

The battery should have a black wire permanently attached to it with a ring terminal. That ring attaches to the frame under the seat.
The main wire harness has a black wire with a ring terminal that attaches to the ignition coil mounting bracket.
There is one other ring terminal jumper that attaches to the bottom stud on the battery box and its other end plugs into a black male connector coming from the wire harness behind the air filter box.

Just thought I'd pre-empt with answers before queries regarding those two wires were raised!
