Question about 2002 Yamaha TT-R 125
TTR 90E 2005 Will not start even with starting fluid. Ruled out the carb. Ruled out CDI box (replaced). Checked ignition switch, kill switch and coil impedances. Plug wire measures 8.5K ohms. Plug cap measures over 8K ohms as well (removed from wire). Is this right? The manual doesn't give a number for the plug cap impedance.
Every component plays a part in the ignition system. Check the wiring as you go. Start at one end and move forward. You have done a lot of work so far. so you should be close. If the igniter is fine and the other components too. Then it would narrow it down to an electrical problem or no signal/pulse to the coil. See if the coil is receiving that pulse. you can use a test light for this test. Pos. will be power and NEG. will be the pulse. With light on the NEG. crank the engine over and see if it flashes. Let me know how its going.
