Hey mike, glad you posted your own topic. Easier to keep track of your problem this way. Ok so have you checked anything so far like the main fuses etc ? Did anything happen like battery issues etc? You want to look at the basic stuff first like all fuses including the main fuses that control the start and dash lights cycle. Then wiggle the ignition key, sometimes the ignition gets worn out and it’s in need of a new ignition. The contacts in the ignition get worn believe it or not and don’t make good contact. Wiggling the key or pushing in on the ignition switch in the on position works. 

Secondly is the neutral safety switches and the safety items that prevent a bike from starting. 

Are you handy with a tester because this will be one of those problems that will require some testing? 

I can get you a diagram for that bike once I know what your up against.  

You will also be able to download the manual yourself after 10 contributing posts on the forum.  

So if it were me I would start to check the fuses and main stuff first like mentioned above and let’s go from there. We also have a member that loves Polaris @JacobSlabach I’m sure he will have something to add here. 

Take a look at the things i mentioned first and see what you have going on. 

Let us know.

You mentioned it will start if pulled or if you  bypass the starter circuit  and jump from the battery to the starter.. That  makes me suspicious of the neutral safety switch,  or  a relay  connected  to the starting circuit. First , do you  have  power  through the  key switch  when  you  have it turned to   start ?  check  that   you  have continuity through the  neutral  safety  switch, and then  through the  starter  relay. I'm sure  you'll find the fault somewhere in  that circuit. The  no  lights  might be related or another problem to trace down  after you get the  start  sorted out .

Sounds good. I’m going to go through the diagram today and see if I can point you in the right direction. I will also post the diagram here for you to use and go through.

The gear indicator switch. It’s located on the transmission. Should have a Red wire with a white stripe. Also should be a purple wire and a green wire with a white stripe? See if you can locate them. This way we can confirm that it’s the correct diagram.

That switch will lock you out of any starting capability if it’s faulty.   You can jump wires to test it and see if you get dash lights.  The red with white stripe and the green with white stripe look like it will bring the dash lights on if jumped together however you should only use a test light or ohms meter to jump these two Incase there’s and issue nothing will blow.

Also the ignition switch. Test the plug for power and see if you have 12 volts at the ignition. If so what color wire has the power it should be the red wire.

your talking about the kill switch @Frank Angerano right?

so if you jump the relay, it starts?  I would say kill switch, ignition, or relay is you problem. 

If the kill switch is bad, then wont it cut power to the plug too?  I say try a new starter relay and see what happens.  easy to check the kill switch and key too tho!  ALWAYS try the simple stuff first even if its not likely...  pays off trust me. 

Also, make sure your battery is not hooked up backwards and the wires have good contact with the terminals.

i dont think polaris's have neutral safety switches.  i know the sportsmans dont.  I can electric start mine in any gear (H,L,N,R,P)

and the older ones were like that too, just had H,L,N,R tho.

I think your right but there should be a lock out of some sort ? I have to take a second look at the diagram.   I would be surprised that it would be able to start in gear.

Your welcome mike. But are you sure it’s the switch ? It would suck for you if you wasted time and money on the switch if it’s not bad. I was only pointing you in possible directions of what the problem could be. So unless you positively identified that as a problem you may be disappointed when you install it. I just want to throw that out there brother. 

Like @JacobSlabach said maybe a kill switch etc ? 

You can do some testing before buying parts to positively diagnose the problem.  Just want to let you know.

      Ok so just picked up an 02 ds 650 and the guy said he couldn't get it to start. He had a shop put new shims in it and I had them checked and they were ok now things I've done is new plugs even though guy had just put new plugs in it.. got new carb 42mm just like the one that was on it.. bought new intake manifold because the one that was on it someone got way to tweaked out and ported the shit out of it excuse my language but yeah so installed new intake manifold and it just won't start like its not getting enough fuel.  Timing seems to be right it does fire every now and again but just barely.. did a compression test today and it was at 90psi.. i know thats low but don't know where I'm losing compression.. valves we at .06 and .07 when checked im lost ive tried everything I know and can't figure it out

      Have a 2001 polaris sportsman 500 4x4 atv and when I put coolant in the radiator it starts leaking from the exhaust. The valves are sealed but it stopped making compression. Do I need to just replace the head? I just rebuilt the hole top end and this is the only thing +valves that I have not replaced and was wondering if that is why it's not starting up. Need answers please.

      So i have an old yamaha bear tracker that was given to me from an old farmer I know. I decided to refurbished it and fix all the quick fixes on it. I am pretty sure that it is either a 1999 or 2000 based upon the original wiring harness. Little did i know when I bought a new to me wiring harness from ebay that it was from a 2003 or 2004. My question to everyone is do I need to have all the stop switch assemblies hooked up? I think there are three on the 03/04 models and only one on the 1999 to 2000. Any help I can get for this would be great. I haven't run it yet due to the motor and crankcase is in two totes.
