Message: [QUOTE="MadArrow, post: 672180, member: 46254"] Ok. Remove the seat and tank if you haven't already. Unplug the three wire connector coming up from the magneto. Should be somewhere around the tank area. Now check the res from black wire to blue, should be about 104 ohms. Then black to white/red, should be 142 ohms. Now blue to white/red, should be 38. If I remember right the last two in my book were switched, just a typo. I think I straightened it out for you though. If you want, black to yellow should be 0.54, but that is just for the headlight so it should have no effect. Also, all those figures have an acceptable range of + or - 20%. As far as voltage coming out it varies with RPM, but I had somewhere between 15-20 VOlts AC with a good hard kick with no spark plug. While your at it check you coil, primary to flange should be 0.22 ohms, and secondary (plug wire) to flange should be 7.2K ohms. Alot of shops will test coils for 5 bucks or so. Good luck. [/QUOTE]
