02 fe501, no spark.

xenri90 · Nov 7, 2010

The thing is, I'm holding my berg in garage at the moment, have been there several weeks now, the weather is 0 to 5 degrees C, in garage same. Anyways, it did start a week ago, installed a new start jet and it started great with choke ON. gave it some Revs, and now, this weekend, it didn't start, checked if plug had a spark, it didn't.
Is it almost clear that the SEM ignition is faulty? Is there any ways to check that does the stator give any voltage or not, any instruments or something ? Also I don't want to believe the sparkplug is faulty, as these iridium things should be pretty bulletproof ...

Thanks.

Hi,

Believe it or not it is true that the stator can fail if left in bad atmospheric conditions, if you have checked all connectors have the stator resistances checked for the correct resistance;
Black to Red 3000 Ohms
Black to Green 165 Ohms.
Let us know your findings.

Regards

Sparks.

that 3000 is a bit unfair Steve? they run at 2800 and they come from you with only 2900! 2750 and below and they are on their way out....

just my opinion of course!

Okey, thanks for info, I'll check the resistance at the weekend.
These stators must be *****, if it can't compete with minus degrees while standing.

Plus or minus 10% form the values given is within acceptable parameters I believe.

at the weekend I stripped the wiring a bit, checked any bad connections, and also the CDI unit which must be tightened nicely to the frame, just tightened the screws and cheked... Also got the multimeter and checked the Ohms between black, green and black,red which came from stator to the cdi...multimeter was showing weird numbers...not anything like 028 or 2800 or 0165 what I expected, anyways the stator cover was hermeticallyclosed and the wireharness goes in there, also is nicely covered and tiffed, so I didn't want to open it.
Spark was back... that was some nice news, the wiring of this bike is also from the year 97 or under, and there may be some bad connections, think it was the problem : ), Thanks for the info everybody
