KLF300 1994 spark plug cap resistance


Go to solution Solved by Params_sweden,

Recommended Posts

Hi! I'm new to the forums :) I'm working on my klf300 that isn't starting anymore. I accidentally ripped apart the spark plug cap, and I'm curious to know the resistance of the original part, it's not mentioned in the manuals. If anyone with a KLF300 could measure their OEM or known working replacement spark plug cap I would be very happy :) NGK for example has spark caps with resistances 0, 5, 10, 15 ohms so it seems to be something that I would like to match as close as possible with the original part.

Thanks,

Pär, Sweden

The test in the book says to test the coil with the cap off the lead, and it should be between 10-16 Kohms..  I suspect the cap doesn't have a resistor built into it.

Use a small split pit shoved up the lead and clipped onto the spark plug and try running it, if it runs ok and doesn't make massive interference to a nearby radio then it will probably have a resistor lead on the coil and it will be ok with a zero resistance cap.

Thanks for your input, I'll give the radio test a try in a moment! Like almost every Bayou owner mine has ignition issues, in my case weak spark or no spark, so I'm trying to rule out everything one step at a time. I ordered a NGK spark plug cap VD05F with 5kOhms resistance, it was like 30% of the OEM part price :)

@Gwbarm Yeah feels good! I bought an aftermarket China part from a Swedish seller, unfortunately it's a no-name product, when I got it it didn't match the image on the sellers site. Here's a link https://www.merafritid.se/tändspole-kawasaki . It came without spark plug cap, the "ignition wire" has a black outer rubber and a white center.

      I had a sudden loss of spark in my 1988 Suzuki LT300E quadrunner and we tried a new plug but still no spark. Then we checked the boot and there was no issues with it. I then took off the coil as I was going to get a resistance reading with a multimeter however I cannot find anywhere what the readings should be. The coil is a Mitsubishi F6T 411. Any help would be appreciated.

      Hey everybody,
       
      My proficiency is with Hondas and Yamahas make me see RED!
       
      This bike is my brother in law's, it has 1199 miles on it and went from running great to dead with no start. Every once and a while it will start and sputter for 2 seconds. It is extremely sporadic when it fires but never runs for longer than 3 seconds. 
       
      Here is where we sit:
      Brand New Fully Charged battery
      Carb was cleaned with air hose and carb cleaner then into the ultrasonic cleaner with Aircraft aluminum cleaner
      New Shindy Carb kit (made in Japan version)
      Cleaned out petcock and gas tank
      New 93 Non Ethanol Gas
      New Spark Plug
       
      It gets a spark through the spark test light every time
      Bluish white spark
      When holding the spark plug 1/4" - 3/8" away from head it will jump and spark to the head
      Good Compression
       
      Here are the readings:
       
      Pickup Coil 519 Ohms (range 459-561)
      Charging Coil 266 Ohms (range 270-330)
      Lighting Coil 0.700 (range 0.702-0.858)
      Spark plug Cap 10.58 Ohms (10kohms
      Ignition Coil Primary Coil 0.5 ohms (range 0.18-0.28 ohms)
      Ignition Coil Secondary Coil 8.20 kOhms (range 6.32-9.48 kOhms)
       
      Would y'all think stator and pick up coil, rectifier or CDI are the culprit?
