[QUOTE="500guy, post: 861956, member: 55263"] 2003 RM250. While riding the bike when instant dead. No spark, changed plug still no spark. Took off tank and there is a broken yellow wire just hanging there, looks like a fresh break. I have the manual and this wire seems to be "extra." It comes from the stator bus, but does not go into the plug (that feeds the CDI). So there are the 6 wires from the stator bus that go directly into the plug (including the yellow wire that is on the wiring digram) PLUS this 7th yellow wire. 1. Is this an extra wire for an accessories that should be left hanging? If not, where does it go. 2. Testing the coil, the secondary value should be 13-20K Ohms. It tests at 5-4M (not K) Ohm. My testor has been sitting awhile so I still need to verify the readings. If correct, could this be the problem. 3. It was late (like 2 am) and I started to test the CDI box. After a few reading that did not make sense, I realized that I had it set to Volts (DC) :bang: . I switched to diode and then got some values in range (or close enough) but several (3 entire rows) that gave no results. I have read that CDI tests are not accurate. OR, did I fry my CDI? Using a Voltage test, I would not think it would hurt it. 4. I did disconnect the kill switch, still no spark. 5. I want to check the ground, but where is it? Thanks, I have races the next 2 weekend and would need to get the right parts ordered today. [/QUOTE]
