No Spark...Got new CDI box...Still no spark?

[NewGuyOldHonda]

Well I ordered a new CDI box for my 1984 200ES. Had power going in to the old one but no power coming out. Plugged in the new one and still no spark. Now what should I replace?

spark plug.

You sure there is spark coming off the stator? Yeah, you got a new plug, right? All wires connected and no breaks? The next thing I would check is the Ignition coil. You can test it with a multimeter if you have one. You need to test for OHM's resistance. There is a primary side and secondary, or plug wire side to the coil. Check the manual to find the correct readings on it. It could also be your spark plug cap or wire, which can be tested also. Good luck. ---- Jon.
