80cc Magnet coil voltage?

[Nesvarbu145]

Build a bike. Everything was good for about 15 min. Now i know that mixture was too rich with oil. But i came back home somehow. And the next morning I have no spark. Disconnected kill switch. No spark. Tested ohms. Looks good but still no spark. Changed spark plug. Still no spark. So ordered new cdi. But ive found the thread that tells if you connect multimeter to blue and black wires of magnet coil and spin the engine it should show about 50v and mine only ranges from 3 to 4 volts. Maybe i misunderstood something. Please help me should i buy a new coil or what?

An extra coil and CDI are always handy to have around. I've had coil issues before, but never a CDI. I seen lots of guys wreck them, it must be the heat.

Ok so i just bought new cdi, spark plug, coil and magnet. Placed them one by one. Still no spark. Please help someone!

Break In - Run 15 min. Now can't start it

Ordered new cdi. Again need to wait few days. Its so strange that i had few minutes ride and now fixing it for a week. And im also thinking could i kill my cdi with my kill switch?

It's hard to help without some pictorial information. Each time you swap a part, take a picture to post. If the engine runs the way it is expected to then just delete the picture, if it doesn't, then we have something to reference.

Go through all your electrical connections slowly and make sure each one is solid and not grounding itself out.

You know I'm wondering if that what happened to my phantom
How do you check with am ohm tester what do I set the dual to. And what should it read.
