1998 Suzuki LTF500F starts then dies

[atvfreak]

Hello everybody I have a problem with my Suzuki LTF500F 4x4 quad it was running & it just shut off now I start it & when I let off the start button it dies does anybody know why my quad will only fire when I have the start button pushed it stays on & when I let go it turns off it only stays on as long as I hold start button?

Sounds like a wiring or kill switch issue to me. Could also be that your secondary ignition is not working. Once you let go of the start button and the engine is running, the ignition gets power from the secondary ignition which is powered by the stator and runs through the regulator/rectifier to power the ignition and charge the battery. While you are starting the engine, the ignition runs off of the primary ignition, which is powered by the battery.

Hello thank you very much for your help changed out stator,kill switch,wiring harness,same problem, so then i started thinking about what you said about primary & secondary ignition so then I started reading the repair manual under ignition coil the coil was the first thing I changed before asking for help thru forum thanks to your suggestion about primary & secondary ignition I found out repair manual says "DO NOT SUBSTITUE COIL" which I put on a hot universal coil found out it didn't work the hard way long story short got a oem coil & it fired right up perfectly atlease I now I have extra parts lol. Thank again because without your help I would have never figured it out.

I am having the exact same problem with my 00 LTF500F. The only thing I changed was the spark plug, and the only thing possibly weird or odd about the primary/secondary system on mine is that I was using a totally dead, unrechargable battery in the quad with jumper cables to another battery. I am gonna put in a new battery and go back to the old plug and see what happens.

Hello have you checked if it has spark at spark plug when you try to start quad let me know what happens? thanks,Juan

If it doesn't work, my best guess would be that your stator is bad, it is what the quad's ignition will run off of after it starts. The regulator/rectifier could also be the issue.

BTW, atvfreak, you are welcome, I did not catch the thankyou post untill now, I am glad I could help.
