Hi all!
well as the title implies, I'm having a pretty rough time. I got a 2000 honda fourtrax 300. I ended up rolling in on a mountainous trail a little while back and had to be searched and rescued out. During the roll, the ignition cylinder got busted out into pieces, brake throttles loosened, the steering column snapped in half, handlebars bent, and oil light busted out. Rescue team couldn't get her going, and ended up leaving it. Next day, went up with a friends wildcat 1000 and towed her off the mountain. Same friend works as an aircraft welder. He welded up the steering column and made one hopefully stronger than anything Honda makes. Now the fun part, trying to get her running to asses damage. I "hot wired" the ignition and get no neutral light/ no crank. I then tested the battery and checked fuses. All good. I then jumped the starter solenoid and she cranks like a bat out of hell, but does not start. This makes me think I have a faulty neutral safety switch?Does this sound correct? I pulled the cover for the neutral switch wires and it seems to be intact, how do I test it? But also, why won't she start ? Shes got good compression , gas, but what I would guess to be is no spark. Sorry, I cant test the spark, as I cant reach far enough to jump the solenoid and ground the spark plug at the same time. Unless someone knows a good technique. Where would y'all go next on this diagnosing adventure? Could it be the left handlebar choke/ kill switch? The choke lever snapped lightly but still can move, so i know it took some impact in the roll. Is there a way to bypass the kill switch to see if that/s the issue? How can I run through the entire ignition/ spark/ coil system to see where the issue is? Thank you guys for any advice you can offer me.

Best Regards!

No neutral light, no start!

Take the kill switch apart, I can't remember if it's a closed or open circuit when OFF. You'll see as soon as you open the casing up. Just bridge the switch and try it, it won't do any harm.

You should have two sensors by the neutral sensor, I'm pretty sure their the same, swap them over and see if that works. If it works then it's a bad sensor.

Personally I'd say you've got a bad kill switch or a loose or broken connection somewhere after the roll over.

Hi Sam, Thank you for your quick response and help. I was really thinking (hoping ) it was the kill switch too. I removed the kill switch. Connected the common and hot wire and tried to jump the solenoid. Cranks but no fire. Disconnected the wires (open circuit ) and tried jumping it again. Same results. I guess the kill switch can be ruled out. Going to order a new assembly anyways, along with new ignition cylinder, while I keep diagnosing and moving down stream. Where would you go next? Still looking into how to run my multi-meter and what testing for continuity means. Sorry , I know I sound like an idiot lol.

Neutral Sensor: Yes I believe there should be a reverse and neutral sensor down there. One has two leads going to it, and the other has one. I can pull those off, pull the sensors, then swap them?I will go look now and see if I can get a decent picture.

Thank you so much for your advice. Hope your having a great day!

Your on the right track, it's a lengthy process sometimes, a process of elimination.

Testing continuity means making sure there are no breaks in a wire. Some multimeters have a continuity setting and will make a beep if the wire is good. If yours doesn't have that then select the 'ohms' function. You will get a random number appear and then drop off to nothing if the wire is good. If the wire is bad you will get no reading at all.

A continuity test is a test to confirm resistance through a wire or electronic item such as a bulb or fuse etc.

Okay thanks , for the explanation. So how can I apply it to this? Where would I start to check for continuity? Also got the leads off the neutral and reverse sensor. But how do I take the sensors out? Can't seem to get a socket in there to remove them. The wires seems to be unbroken and making good contact. I've read on another discussion that a person suggested to another, to just splice the neutral wire into a ground on the frame. Would you recommend that I try that?
