WAIT WAIT WAIT!! I just went back and read the original post. You said you fear your stock coils may be going out soon?!? You mean your original ignition is working but you want to tear it all out because you FEAR that it could go out soon?
That is like when you clean up your garage and you throw away a quart of oil because it's old.
Don't stare out of a window at your bike on a cloudy day for fear of rain.
All of the replacement internal coils suggested here lack the floated ground wire feature that would normally power your brake lights. Yes you will want brake lights the day after you install the aftermarket internal coil and the bike runs.
Now to get brake lights back you have to leach power from your Red head light wire, replace both your brake light switches, Eliminate the grounding wire in the headlight and route that wire back down the frame to your black brake light wire.
Then when your all done it sucks because the brake light causes the headlight to dim when you apply the levers.
To cure that you start fucking with LED tailights but those want to blow cause the need a diode installed to soften the AC wave.
It's a whole fuck storm of things you have to do that is called the moped hobby that is best experienced by just trying to learn to make all of your stock features work correctly at first and understand why they behave the way they do.
I have found over the years maybe 2 Peugeot stock ignitions that were bad. I try to run the stock points sets on all the bikes I refurbish for sale.
By the way does your bike start and run now?
