I measured resistance on the coils, but I don't have anything to compare to. I get:

Internal yellow coil:

- Blue wire to grey: 300 ohm

- Grey wire to ground: 51 ohm

- Blue wire to ground: 256 ohm

External Pietcard HT coil:

- spark plug boot to ground: 8.6K (including 5k NGK resistor boot)

For reference, my CEV coil without the boot measures 8.2K.

No. The 2013 I had crapped on me once while going down a hill (I guess it revved to high) so I ordered a 2041 to replace it. When I tried the bike a couple days later it worked again so I left the 2013 in. That was last summer.

On my last ride the 2013 died again so I thought I'd finally replace it with the 2041. I just replaced the 2013 with the 2041 without changing anything else. With the 2041 I managed to ride for 50 meters then it died. I don't have a spark since then.

Last night I cracked open the 2013 box and every component measures ok, except maybe for the silicon-controlled rectifier which I'm not sure how to check. I might try to put it back to try if it works. Maybe I fried the 2041 box with a badly screwed-in spark plug cable? I Don't know.

AFAIR the ground was sound, but I'll check again tonight. Yes I have a 5K resistor boot (NGK TB05EMA).

I get continuity between the motor case and the bolt holding the external HT coil when tested with a multimeter. The CDI box and external coil are grounded to this bolt.

I’ll remove the flywheel tomorrow to check the internal coil.

Unfortunately no. But I have a spare stator with points installed (the kind with the internal HT coil) and a spare 12V lighting coil that I can put in the meantime.
