Check your charging voltage at the battery when it is running. Let us know
Well my voltmeter from hobo freight won’t lock down a set number. It’s bouncing from 13.5 to 18 lolCheck your charging voltage at the battery when it is running. Let us know
Possibly. I was having issues with the winch letting it out. Like the lights, digital dash, annd instruments flicker and it almost dies when I let the winch out. Doesn’t do it when I bring it in. I figured that was the winch relay and was going to check that but maybe it’s regulator? Also, it might be a 2005(dark green) because it has the digital dash instruments and not a 2004. I’m not sure if that makes a difference.It may be your voltage regulator is shot
I’m pretty sure that you’re onto something. I did just use the meter and It was just fine but I’ll check when I get home. Remembering the winch issues, I went ahead and ordered a cheapy rectifier off Amazon with good reviews about the unit and plugs for arctic cat to get here tomorrow. Fingers crossedCheck your meter on your car or truck. If you get a consistent voltage when running , it’s not your meter. VR/Rectifier is a cheap part.
Well, I got the voltage regulator on Friday was pretty excited to put it in only you did absolutely nothing same exact symptomsCheck your meter on your car or truck. If you get a consistent voltage when running , it’s not your meter. VR/Rectifier is a cheap part.
Possibly your stator or flywheel? I know the 400’s have the issue with magnets coming loose and causing issues with starting and running. If you haven’t upgraded it, that could be one of the things? In order to test the voltages you need a DVA. Otherwise you could ohm out the 3 pins I believe and see if they give you the correct readings. AC manual shows the correct ohm readings you should get.Well, I got the voltage regulator on Friday was pretty excited to put it in only you did absolutely nothing same exact symptoms
The part was 26 bucks so no biggie. I’d rather not return it just get a more expensive part and have the same result. It actually starts strong like it should with the new carb. I did put in new jets O-rings, small diaphragm air fuel mix needle in the factory carb and tried to put it back on but it still started like crap so the electric choke might be bad in that but with both carbs, the second that you give it any throttle and it bogs and spits. I’m about ready to throw in the towel and bring it to somebody that actually knows what they’re doing with small engines so if anybody knows a decent place in the Twin Cities, that’s not gonna take me to the cleaners I’d like to bring it there this week so I could have it going by memorial day if possible.Possibly your stator or flywheel?

But it could also just be that you got a Amazon part..I would go OEM if you can. Ebay has good used parts. Just go OEM I don’t think they’re crazy expensive..shouldn’t be.
Yeah it could be that electronic choke, I haven’t figured out how it works yet either.. no good information online may have to look through the repair manuals.The part was 26 bucks so no biggie.

Yeah, the other carb came with the automatic choke installed and like I said fires up and runs just fine so I was initially pretty excited up to about an eighth of a throttle… I did mess with the air fuel screw factory says all the way in and then back almost to turns and that’s what I said it as initially on both carbs but really it has no impact on the way that it’s running right now there’s definitely something up. I can give it to about eighth of a throttle and it sounds like get it up to about a few thousand RPM before it starts to bog out so I can move it around and can’t get it going up to about 15 miles an hour stop before I start having issues.Yeah it could be that electronic choke, I haven’t figured out how it works yet either.. no good information online may have to look through the repair manuals.
So, the other carb that you had put on actually came with a new already installed choke? You just had to plug it up?
Honestly I think it’s worth messing with the air/fuel screw..you’re almost there. The dang thing starts and idles, you are just missing one little thing.
I guess that is a possibility but the 400 and 500 are completely different motors and everything I’ve read about that magnet stater issue doesn’t apply to liquid cooled motors but what do I know? Like I said, I’m almost to the point I was just trying to bring it in somewhere.You are in this year range as mentioned

Arctic Cat 400 Intermittent Spark Video (Flywheel Issues)
Hey guys, Here is a video I shot on troubleshooting an intermittent spark problem I had on a customer's 400 4X4 automatic. Hope this maybe helps someone down the road. Link to video below,www.arcticchat.com
My man I wish I had the confidence to know where TDC on which stroke it is or how to perform a leak down test and what tools needed to do that. Or how to adjust the valves.In this case, you definitely have some timing off. Have you checked TDC position and made sure piston is at very top?
Once you check that out do a leak down test at TDC. Pressure should hold good in the chamber with valves closed at TDC. If you hear leakage, your valves are out of spec. Use your eyes and ears. That’s it you’re willing to do it.
My money is on valves now.
You’re on a forum asking for help, and obviously want to save money. Forums are great for this. The information is out there, you just need to apply it.My man I wish I had the confidence to know where TDC on which stroke it is or how to perform a leak down test and what tools needed to do that.
