2001 Sportsman 700 Twin. No start

I will be the first to admit that I dont know much about ATVs. I am working on my bosses atv and it will crank but will not start. It cranks but no spark. I found that the wires on the ststor were melted off so replaced stator. Still no start. Since then we have replaced regulater and ignition coil module. Still nothing. We checked the kill switch and found corrosion at the plug in. Replaced switch this morning. Still no start. Found it will start if I disconnect the black wire from kill switch to coil. As I dont have any manuals to look at I am totally lost. Can someone please point me in a direction to look?. Thank you in advance.

2001 Sportsman 700 Twin. No start

Take a look at your ETC contacts in the throttle housing, if they are closed it will also cause no spark. While I'm not familiar with these early year twins, I do know there are ignition kits both OEM and aftermarket since the originals were not the best design. Has one of these kits been installed?

I don't have a book for the 700 handy so I can't look at wiring diagrams. I would imagine it is the same as the other '01 machines though.

On my Magnums, if you can start it with that black wire removed and the kill switch is good, then the problem is probably the rev limiter. On the magnums, it is a separate part however they do not come with a speedo either. When I put a speedometer kit on one of mine, it replaced that with the same function in the speedometer itself. I think my 600 book covers the 700 too. I will look when I go out to the shop.

Edit: My book does not show a 2001 700. It starts at 2002, but there is no separate rev limiter. Everything goes into the speedometer

No sweat about the year.....If you don't already have one, you will want a repair manual with the wiring diagrams in it. Mine is a Clymer that covers the 600, 700 and 800 Sportman models. You are gonna have to start tracing down wires. If everything in the speedo works then it could just be a shorted wire in there somewhere.

If it starts with the black wire off the kill switch it sounds like you may just need a switch.

The key is that it will start with the black wire disconnected at the CDI/Coil unit. That is the kill switch wire. If you've already replaced the kill switch, then the problem is a short to ground in that black wire somewhere along the harness before it reaches the CDI/Coil. My guess is if you trace it carefully, you'll find a spot where the insulation is worn off and you have a short to the frame in that wire somewhere. Start there and totally rule out that black wire grounding before looking at anything else! Let me know what you find. The Sporty 600/700's are notorious for stator source coil failures and failures of the combined CDI/Coil unit, but that doesn't seem to be the case here.

Having the same issue with my 03 700. New CDI (aftermarket) and new kill switch (Polaris). When Ohmed, Black wire to kill switch will show ground until you turn the key on, but if you start it with the ground wire disconnected, it will not kill the motor when you shut the key off. I need a wiring Schematic. . .

Strange...Here is a wiring diagram for a 2002 Sportsman 700, pretty much the same.

Here is what I figured out. kill switch (KS) in run position, key off, kill wire is grounded. KS in run, key on, have battery voltage. According to the schematic, at the key switch, do you see the connection being made between c-d, and e-f or c-f, d-e?
