ATV Repair

[chads]

Any one know of anyone who works on ATV's in western New York, Orleans County area?? 

I have a 2003 Suzuki Eiger 400 LT-A400F that intermittently shuts off when running. It just quits, and sometimes backfires. 

If you shut the key off and turn it back on it starts right up??  I think it may have something to to with the Voltage Regulator\Rectifier, but I suck at electrical trouble shooting.

 

Any ideas are greatly appreciated.

I assume since it's an 03 / 400 that it's carbureted? 

In my experience with simple air cooled / carbureted machines, if something is randomly shutting off and turning right back on, I would look towards loose connection on safety switches, or grounds. Since if you cycle the key it starts right back up, I would maybe focus on the ignition cylinder and its connections.

Great idea, I never would have thought of this. That makes so much sense.

 

Thanks a bunch.

i would think if it was voltage regulator u would see that the battery not getting charged or an over charge.... at least thats what i found ,,, i would go with a short in kill switch or ignition does it happen when your turning that would cause wire harness to move .....

I'm not convinced it's electrical

I had one do this shutting off randomly thing a few years back.... It would just shut down while riding it and not restart for several hours... I suspected the CDI module failing once it warms up.  It did it, so I I removed the CDI and tossed it in the freezer for 15 minutes, then put it back on the machine and she started right back up.  Replaced the module with a new one and it never did it again.

PS.... I firstly checked for powers and grounds, which I had.

I would check to see if it has a cdi box or control module of some sort. Sounds to be electrical. Since it fires right back up.

Change out that Vacuum Petcock, plenty of videos on YouTube they are notorious for what you describe

Just wanted to reply that the resolution was a faulty Voltage Regulator\Rectifier. It was putting out the wrong voltage and fried the Battery.
