HELP!!! Stuck in the bush, KTM 300 no spark!

Ok further checks this morning
Removed coil from bike, trimmed coil wire at coil end a fraction, still no spark

Cleaned all contacts for coil to frame, reinstalled. Still no spark

Re tested coil resistance
Primary to grnd 0.00 ohm (if set multimeter to 200 setting I could get 0.09 ohm reading, settles to this after starting at 1.4 ohm and dropping to .09???

Secondary now reads 11.1 ohm

Stator readings are
Pulser coil: 100 ohm
Exciter now reads 9.0ohm

I did a coil and a starter switchblock on my old 530.. Nothing worse then no spark... Sounds like you are making headway tho..

Goodluck....

I warmed up my bike and went to test it all good. Talked to the group I was about to lead than went to fire it up and nothing. Went through a heap of things on the trails (fuses, switches, plugged stuff in and out, inline fuel filter, bypassed stuff) and no joy. Got home and found another fuse in the airbox I didn't know was there. Probably already tried it but worth a shot Good luck

interesting Noodle, I had changed out a fuse a couple of weeks ago, but I didnt think a blown fuse could affect kick starting the bike? just electric start and lights etc??? I still have electric start etc...?


on closer inspection of the stator this morning, I noticed the pole between the pulse / exciter with the black coating looks to be heat affected, like it had started to burn out? the rubber like coating is all smooth, but around the windings looks a little burnt / textured....given that it was only reading 9ohm (should be 12.7 +/- 15%) i think this is what has happened. Ive left it at the shop for them to verify before spending the $350 to replace.

wonder if the wet mod contributed or not? or if just a freak failure?

I dont know about that as my bike doesn't have a kicker but we couldn't even jump start it.

there is no reason to put fluid in the wet mod, just adding a top vent and blocking the lower hole stops all the crap getting inn IMO

Thats what I was thinking ggg, just sealing it all up as a wet mod, and greasing the gears periodically.
Now deciding if to go OEM stator again, or Trail Tech 100w DC, or get it re-wound.
I guess comes down to dollars, but at the moment the TT comes in nearly $100 cheaper than OEM.

coil should be around
primary 0.5 ohms
secondary 10-16 Kohms ie 10000-16000 ohms

i'll spell it again
secondary 10000 -16000 ohms
even 6000 ohms should be ok

Maybe try another coil, foureys are the same
Did you try voltage tests from the stator?
I'm guessing the stator is fine.

there are two fuses in the airbox of a lecky 300, one is a spare.The fuse is only for the electric start, they will not stop the bike firing or your lights working

Thanks Steve, I removed the coil this morning and cleaned all connections, removed coil wire at coil end and clipped a couple of mm - reinserted. still no spark.
I re tested it and got the following

Primary - white&blue to grdn =0.08ohm (dial set to 200)

secondary - white&blue to Ign = 11.1Kohm.

will see if I can get another coil to test. will hold off on a stator purchase till this is eliminated.

Just had it confirmed that the stator is the culprit! Have ordered a trail tech high output replacement, as its cheaper than oem - with equal or better quality and has the extra headroom for running grip warmers, fan etc.

Thanks for your help everyone (particularly Steve)
