Steve-2018 Don't forget the simplest things first. 1997 Fourtrax300FW was running fine, stopped it to split some firewood, wouldn't start back up, plenty of fuel. I pulled the sparkplug, zero spark. I read a couple forums which made it sound like the most common problem for no spark was the CDI. From a YouTube video, I followed the instructions and used the multi meter Ohm meter to check the resistance on the two coil leads and the reading was about 0.8 as expected for a good coil. Ordered a CDI, replaced it, still no spark, but when I was checking it I noticed I was getting a shock holding onto the plug wire. Used a multi meter to check the spark plug (from instructions on YouTube videos) and there was no continuity on the spark plug. Replaced the spark plug, turned the engine over with the plug grounded to the cylinder head, visible spark. Then reinserted the plug, and it started right up.

The moral of the story, if you don't have a spark, you may want to check the plug, or replace it first. That was the cheapest option, and it would have saved me the time of pulling the front cargo carrier and plastic off to get to the CDI. I hope this helps someone else down the line.

lake_charles_muddbogger30 have you looked to see if you simply bumbed the kill switch on accident? if done that before.

ChrisBuckH All of the connections in the box are cleaned up and have a good connection and still nothing.

ChrisBuckH No, I don't have a service manual for it.

L84MUDN If you haven't, pull open the black "waterproof" box under the front plastics where the handlebar wires meet to the main harness. Last 2 older honda's that showed up with no start but crank over were bad wires in that box. I just soldered those together and cut out the plug-ins because they couldn't have been cleaned up.

It's the very first place I'd go. Found out the hard way on my '88 300.

toodeep The older machines will turn over with the kill switch in the off position, nothing wrong there. Do you have a service manual for some testing?

jeepwm69 Got a test light? You sure you're getting power at the ignition switch? Power to coil?

ChrisBuckH Still not getting any spark. So far new parts include: coil,CDI,voltage regulator, battery,starter, and plug. One thing I did notice that was odd is that the motor will crank even when the kill switch is in the off position. Help!!!

ChrisBuckH All connections in the battery box are good. I took them all apart and put them all back together. What's the easiest way to go about testing the stator?
