Send a PM to DEET. He is the Stator Mastor . . .
IF it isn't one thing, it's another.

i might be misunderstanding but was it just one coil you replaced? but now you're not sure where to hook them up into the wiring loom after re-fitting the stator plate. The colors should match up to plugs in the loom of those same colors so maybe were not talking that. Starting again i assume we're talking points ignition still in "74 on the 250 so the single wire from the stator ignition source coil would just go across to the condenser. if it goes to the black in the loom it'll still have to find its way back down to the condenser via an ajoining black wire.
Colors as i recal--& it's been a while--black is ignition for sure--from stator coil & ends up at the coil under tank eventualy, or directly if you just want to see if it sparks & runs.--green is daytime charging for battery--green/red stripe is a higher rate of charge & might be swapped into the green plug if more daytime charge needed but only 'guessing'. could be hooked in through the switch when lights turned on--then yellow is lights--if blue is a light color blue it should be the neutral light switch but in saying that i'm not sure if they had a neutral light?. I'll leave it to 'DEET' now i've confused things. Just found a diagram on the net & see it's the same as up here on the site but i go cross eyed looking at them so i give up.

.

My lighting coil has two wires - Green and Green with red stripe. One connected on each end. of the lighting coil.
My source Coil has 2 wires - Yellow coming out and black going to condenser.
My points wire is blue and leads to condensor.
The condensor has 3 wires connected to it, black and blue. The 3rd is a black wire that runs up to the connector.

I hope it helps.

the black wire from the stator connects to the coil. the black is the ignition wire. the kill switch wire ties into that as well. the kill switch when activated grounds the black wire from the stator and this kills the spark.
