Peugeot 103 le partie CDI trouble

Thomas Mash Potatoes /

I'm having trouble finding the spark for my 103. I've never done electrical work like this before. I made the attached wiring diagram & a friend assured me it should work. I incorporated cheetahchrome's chili stained wiring diagram. I wired it all up & got spark on my first check with a drill & then never again. So I took out all the extra stuff & wired just for spark, still nothing. I checked the parts with a DMM & the ignition coil on the stator came out to 98-99 ohms at 200 mark on DMM. The high tension coil came out to .1 ohms. Checked online & Google says it should be between .4-2 ohms. Ordered a second one thinking I had my problem cornered & that one came out to .1 ohms again. I checked it against my known working Puch ignition coil which came out to 1.67 ohms at 200 mark on my DMM. I don't have a separate CDI box to test that against. I have it all grounded to the subframe as seen below & the engine grounded to the frame. Are both high tension coils bad? Do I need to ground the subframe to the frame? I'm at a loss.

Why not mount the known good coil from the Puch and see what you get .

I'd have to say , from your test results that your two other coils are bad .

Unhook the kill switch, use the decomp or choke to kill engine.

Check your grounds and no paint, bare metal. Some drill motors can't turn fast enought.

The Cdi box is bad, the HT coils are solid when new.
