Thanks Zombie!
I'm trying to figure out two things.
Is the pulser coil working?
is the ignition coil working?
I get a really lame spark, if at all. sometimes it will turn over for a few seconds with no spark, then almost as soon as I let go of the starter button, I'll get a single spark. Fully charged battery reading about 13V.
history:
I've had starting issues for about a month now. replaced spark plug, vacuum petcock, and then after a shop cleaned my carb, it failed again.
last sunday I got it started after a carb (Keihin) and intake (UNI) replacement, rode to my buddy's house who is a KTM mechanic. He helped me dial in the idle sped and fuel mix.
I rode it great for three days (a little hard to keep her idling cold, but once warm, perfect), but thursday morning it wouldn't start, just turns over and over. I get gas to the carb. but really weak/no spark.
Killed the battery trying it. charged the battery, and tried again this morning. nothing. still lame/no spark.
That seems to be the pattern - it will run great for a day or two and then nothing. I ride home with no sputtering or other signs of anything wrong, turn her off, then 10-12 hours later, she wont start at all. eventually somehow I keep getting it started again, only to repeat the pattern.
The high voltage coil has some odd resistance readings, so I'm questioning that. and I can't figure out how to test the pulser, since the manula calls for testing between the blue/yellow and green. there is no green, but I also read here somewhere that green always jsut means ground. I still can't get a decent reading off the pulser. but earlier you mentioned bad wires/loose connections, so I'm trying figure out how I can bypass the wire harness in places to see if it's really a bad coil, or bad connection.
I couldn't get a clear enough picture of the wiring diagram to know what connections to jump.
Do you know if I should be able to read the pulser coil signal while turning it over? I have a multimeter. I can't tell where the pulser coil wire is supposed to go after it comes out of the engine case and into the harness. I'd like to connect it directly to whatever it's supposed to connect to and bypass the harness.
Thanks bilyum for the recommendation about the condenser. I can't see where there might be one, and that wiring diagram is too dang low resolution.
Zombie, does your wiring diagram have a good enough res to read?
Thanks!
