No spark 86 YFM 225. Help!
I have a 1986 YFM 225 Moto 4 with no spark situation. Replaced stator, pickup coil, CDI and frame mounted coil and still nothing. Tested the switch and that seems to be working. Am I missing anything? Im pulling my hair out!!! Anyone else have this situation?

Checked all your grounds?

did you ohm your new parts out? I have seen bad stators out of the box
|
That I did not do but good idea. Do you happen to know what the ohm reading should be?

One thing that I did notice is that there are 2 in line fuses that come out of the harness on the right side of the ATV. One of which is a circuite breaker and the other one is an in line fuse. The in line fuse looks to be good with no breaks in the element. The other "circuite breaker switch has small round red button plunger style. Would either of those cause a no spark situation?

stator : .28 ohms with multimeter set at 20k and 281 set at 2000. pulsor / pick up : .40 ohms with multimeter set at 20k and 406 set at 2000 ignition coil: 2.3 ohms with multimeter set at 200k (red lead in sparkplug boot and black lead grounded to engine block). .8 ohms with multimeter set at 200k (red lead in primary wire and black lead grounded to block.) does anyone know if these sound right? went back and checked out all the grounds and all look good. Checked run / off switch again and that seemed to check out too. |
I would just call the Yamaha dealer and ask them usually they will give you the readings. But I buy allot of parts there so they are pretty good to me
